The Lubrication Device of the Ball Mill

The lubrication device is very important of the ball mill. When the main bearing of the ball mill works, the stale lubrication device is very necessary. The large scale ball mill often uses the oil pump for forced circulation lubrication. The lubrication of the main bearing of the ball mill can use the dynamic pressure and static and dynamic pressure. The hydrodynamic lubrication can be divided into the oil pump and the oil ring with oil. The main bearing of the ball mill is composed of the bearing cap, oil scraper plate, platen, eyehole, thermometer, bearing, spherical watts and the oil level hole. Lubrication of these expensive, large open gear systems presents a unique challenge due to the harsh environmental considerations, as well as heavily loaded conditions. Grinding or pulverizing mills are exposed to cement dust, mineral dust, coal dust, temperature extremes and heavy loads. These severe conditions magnify the need for superior lubricating products. Each slide ring runs in a bearing with two self-aligning and hydrodynamically lubricated slide shoes. One of the slide shoes at the drive end holds the mill in axial direction. In the others, the slide rings can move freely in axial direction to allow for longitudinal thermal expansion and contraction of the mill body.
The lubricating oil enters the bearing from the inlet pipe and the oil is injected into the hollow shaft. Then the oil is sent to the bearing bush. The lubricating oil in the bearing housing flows back from the oil return pipe and forms the closed loop fuel supply system through the filtration device and cooling device. The lubricating effect is very good. The oil level hole is used to check the amount of the oil in the fuel tank. Since the rotating speed of the milling machine is too low, the oil film generated by the hydrodynamic lubrication is very thin, which can not reach the liquid friction lubrication but the semi-liquid friction lubrication. The spare oil ring is installed in the milling machine for better stability and safety. The large and small ball mill uses the oil circle with oil lubrication.

Cause and Solution for Temperature Rise of Ball Mill

The rising temperature of the sliding shoe of the ball mill may make the viscosity of the lubricating oil reduce and make the carrying capacity reduce. The rising temperature of the sliding shoe of the ball mill may even cause the dry friction. Seriously, the bush may be burned. The rising temperature of the sliding is mainly from large amount of heat generated between the inner grinding body of the milling machine and the sliding. Part of the heat is taken away by the materials and the gas. The other part of the heat sends out through the cylinder. The heat of the cylinder body transfers to the sliding ring so that the temperature of the sliding shoe increases. In addition, the temperature of the environment is also a very important factor affecting the temperature of the sliding shoe.
In the design process, we can take some technological measures to reduce the temperature of the sliding shoe of the ball mill.
First, install the sprinklers in the ball mill can reduce the temperature inside the mill.
Second, lay the insulation materials under the liner of the end of the ball mill. The temperature rising in the mill comes from the guide of the heat in the mill. The temperature of the cement at the end of the mill is the highest, as a result, we should lay a layer of insulation material with impact resistance and high strength to cut off the heat transfer to the milling machine and reduce the temperature rising of the sliding ring.
Third, increase the amount of lubricating oil for the lubrication system and increase the cooling area of the cooler. The lubrication of the bearing of the sliding shoe uses the high and low pressure oil supply. Generally, before the start of the milling machine and after the stop of the milling machine, high pressure system is used for oil supply. After the machine is in normal operation, low pressure system is used for the oil supply. The low pressure system piping can be designed to three ways.

Hongxing Impact Crusher Is Favored by Sand Plant

The iron ore resources are very rich in China, and China has the largest ore classification, such as the hematite, limonite, sand iron ore, pyrite, ilmenite, phosphorus, iron ore and other varieties. The mining mineral processing equipment for beneficiation can maximize the grade of the iron ore as China's iron and steel manufacturing raw materials. When the iron ores are in the crushing process, the crusher machine is firstly used to complete the crushing operation. The common equipments include the jaw crusher and impact crusher. The impact crusher produced by Henan Hongxing Mining Machinery is made of the casting steel shell and the steel plate. The structure is durable, which is more suitable for the installation of the plate hammer.
The impact crusher is a kind of crusher machine which uses the impact energy to crush the materials. The impact crusher has very wide use, which is one of the indispensable equipments in stone production line. In the crushing process of the impact crusher, the limestone is wrapped by the wet materials so that the dust reduces. The viscosity of the mixture of the gravel and the wet soil reduces and the mobility increases, which can reduce the blockage of the materials. The mixed crushing process of the impact crusher can reduce the stripping of the surface soil of the limestone. The use of the ore resources becomes full. The processing of the two materials can reduce the construction and running costs of a set of processing system. The cement mixed crushing process can ensure the requirements of the discharging particle size of the materials to prevent the clogging phenomenon of the whole crushing cavity to ensure the smooth running of the whole system.
As the professional crushing equipment for crushing the iron ores, the quality of the impact crusher directly impacts the quality of the impact crusher so that the shell of the impact crusher is durable. There is liner installed in the crushing cavity which can effectively protect the crushing cavity of the impact crusher. The liner is made of the most advanced and durable manganese steel.

Impact Crusher Brings Development for Cement Industry

Some analysts have pointed out that as the domestic economy has stabilized, the cement industry in the first half of 2013 is expected to usher the profitability of the industry. According to the statistics, the total investment plan of the cement industry nationwide project investment amounted to 294.3 billion yuan in first 10 months in 2012, which decreased of 3.8%. The cumulative investment in new projects amounted to 63.9 billion yuan, which decreased of 38%. The cement investment in fixed asset is 114 billion yuan in first 10 months, which decreases of 4%. From the different areas, the cumulative year-on-year growth rate is 17% in northwest region. The cumulative year-on-year growth rate is 24% in southwest region. With the acceleration of the Development and Reform Commission about investment projects, such as infrastructure and steel industry and the advance of urbanization and western development strategy, this series of favorable factors will open market space for development of the cement building materials industry in China. In addition, the cement industry is closely related to the crusher machine industry. Affected by expanding market demand, the crusher industry's sales market will be opened. In the cement production process, the limestone has become the most commonly used material for the enterprises. Most of the limestone should be crushed and grinded before it is used to make cement. In the general crushing process, large amount dust will be usually generated, which will cause by environmental pollution. Since the cement enterprises are faced with the pressure from the Ministry of Environmental Protection, the quality requirements on the cement production equipment are higher. In addition, the silicon content in the limestone raw material for the production of cement has strong attrition for the hammerhead of the crusher machine. If the content is abnormal, the crushing process will become more difficult. As a result, the cement plant should choose the crushing equipment with high-tech content, high throughput and fine environmental protection. The crushing equipment should not only greatly reduce the running cost of the cement production line, but also should provide a favorable protection for the efficient production for the cement enterprises.
To deal with the upcoming market demand and alleviate the environmental pressure of the cement enterprises, Henan Hongxing Mining Machinery has introduced a lot of mining machines with novel design, stable performance, easy operation, long service life, low energy consumption and low emission.

How to Correctly Select the Beneficiation Process

Before the ore beneficiation process, the beginning stage of the test work is the most difficult. The research on the composition characteristics of the ore materials can help experimenters faster and more safely choose the beneficiation method and process. At the start of the study in the laboratory stage, it is best to adopt the effective methods in industrial production. When the sorting indicators are not satisfying, it is worth the potential of new technology to develop applications.
The first step for processing the ore is the crushing process, grinding process and the related sieving and grading operations. For most of the ore, the purpose for crushing and grinding is to achieve the dissociation of the mineral particles monomer. If the ore needs to be finely ground, any conventional method or process can be used to crush the samples into the feeding size of the laboratory grinding machine. Conversely, if the mineral ore gathers sufficient amount of particles with coarse particle size, the gravity concentration is very necessary. The crushing and grinding processes should adapt to the sorting process. In addition, the over crushing phenomenon should be avoided.
If the useful mineral particles are too coarse and there is great density difference compared with the gangue, you should firstly consider the gravity concentration. The most commonly used gravity concentration equipment is the heavy media beneficiation machine, jigger and the shaker. Only some sand deposits may use the long chute centrifugal concentrator, the cross-flow belt chute and other fine gravity concentration equipments. The entire process is based on the gravity concentration. In addition, in order to reduce the influence of the particle size and choose different devices according to the different granularity, the grading operation is very necessary before the gravity concentration.
Flotation can be seen as a universal principle. Almost all industrial minerals can be recovered by flotation. The separation efficiency for the symbiotic mineral is also not comparable. For the ores which are difficult to depend on the gravity concentration, the flotation test should be arranged. The scope of application of magnetic separation is very easy to make a clear judgment according to the magnetism of the minerals and the magnetic tape granularity. For example, the wet weak magnetic field magnetic separation method is mainly used for the recovery of magnetite and the pyrrhotite.

The constant update and the further deep research on the control methods of the ball mill and the improvement for the structure and the technology about the cement ball mill are based on the characteristics of the control of the cement ball mill. The control for the cement ball mill is complex. There are three requirements for the control of the cement ball mill. First, the storage amount of the materials inside the ball mill should be fluctuated in very small range. Second, the adequacy of ventilation should be adequate. Third, the production temperature should be appropriate. In the detailed operation process, there will be many difficulties. For the control of the constant feeding amount, there are higher requirements for the materials in the wet grinding process.  For the properties of the materials, the distribution and the particle size of the materials are changeable. It is difficult to grasp the particle size and the distribution of the materials with traditional and the single changeable way. As a result, we should deeply understand the control methods for the cement ball mill to better improve the ball mill in the actual operation.

The Importance for Local Design of the Ball Mill

The local optimization of the ball mill eventually can enhance the production effect of the overall device. The experts of Henan Hongxing Mining Machinery have taken great efforts for the in-depth analysis about the design and manufacturing technology so that the most advanced knowledge about the ball mill can be popularized in the production activities. The plain knowledge about the ball mill is very important besides the in-depth state-of-the-art ball mill technology, which will be very helpful for the actual production. In the actual operation, we should observe and record the knowledge about the ball mill. There is a way to improve the production activities of the ball mill besides the in-depth and the simple knowledge. This way with great innovation can make the simple application method transform to the in-depth technology to expand and change the production range for the production of the ball mill. We should select the improvement method according to the production situation in the production process.
In the use process of the ball mill, the use can be actually combined. Such combination method is used to overcome many problems in the production process of the ball mill. Of course, this kind of modular production is used for the ball mill with miniaturization. Now the common miniaturized ball mill combination can be used with the ball mill in tandem. Each way has its own form. The series connection for the ball mill is for the order for the position of the ball mill. The grinding process increases. The parallel connection of the ball mill includes two small ball mills. The materials with the same nature are grinded in one milling machine, while the materials with the other kind of nature are grinded in another ball mill. After the materials are grinded, the materials can be mixed. For the complex series-parallel method, you can combine the milling machines according to the actual situation, which can not only reduce the investment on the system, but also improve the properties of the materials to some extent. In addition, the working efficiency of the ball mill can be greatly improved so that the we can have the strong control for the production process.

The Crusher Machine Can Be Used As Mixing Machine

We can think that the crusher machine is composed by several sections. The materials are the products for the crusher machine. In a mixing cycle, some of the materials in each segment move toward the product end of the crusher machine. However, the other materials remain in this segment. The crusher machine can be used as the mixing machine in for the internal crusher process. There are two basic mixing forms, namely the flowing mixing and the ideal mixing. However, the dead area by using the limited plunger flow mixing for the unique mixing and the ideal mixing can made the basic mixing form change the form.
The features of it are as follows: no isolation, no sediment, no settlement, no pressure groove and homogeneous mixing. It overcomes the problems which the conventional agitation tank can't solve. Its advantages are as follows: low energy consumption, little medicine consume and long working life. It is widely used in beneficiating metallic and non-metallic ore, gold leaching, metallurgy and chemical industries. It is most suitable for mining mixing which density is less than 30% and for the mixture of ore pulp below 1mm and medicament below 0.5mm. Also it can be used in mixing non-metallic ore.
If the crusher machine is used as the ideal mixing machine, the screening for the product is the screening for the whole crusher machine. At any time, the mixing conditions will not be changed. At the same time, there are some materials moving towards the feeding end of the crusher machine reversely. The crusher machine can also be used as a single ideal mixing section so that the calculation can be simplified. We must consider the distribution of the residence time of the materials in the crushing chamber in the crusher machine.
The crushers produced by Henan Hongxing Mining Machinery have safety protection system that connects with the power and motor so as to obstruct overload. These products are appreciated for easy maintenance, easy installation & debugging and low power consumption.

Bottleneck Period of Domestic Machinery Manufacturing

In recent years, the domestic machinery manufacturing industry has got further development, but there is still a gap between the our country and the developed countries in terms of the innovation capability, industrial base, industrial structure and mode of development. Some of the problems have become the bottleneck of the machinery manufacturing industry.
The capacity of the independent innovation is significantly weak. At present, although the scale of China's machinery manufacturing industry has ranked the first in the world, the high-end equipments still can not meet the needs. We have to import a lot of equipments. Every year, the foreign exchange of the imported machinery products is up to hundreds of billions of dollars. In the industry, the medium low-end has excess capacity, while the high-end products are seriously insufficient, which can not effectively the upgrade of the products.
The basic development is seriously lagging behind. Compared with the host products with rapid development, the development of the infrastructure components, high-quality special materials, automation systems, test instruments, CNC machine tools and the basic manufacturing equipment in the machinery industry is still lagging behind, which has become the bottleneck for the development of the high-end products. Especially the basic components has not attracted enough attention.
The development of modern manufacturing services is slow. From the physical output, compared with the industrialized countries, the current production of many of our machinery products has been the highest in the world. From the saleroom of the whole crusher machine industry, especially from the economic benefits, the advantage is not obvious. The large difference in terms of the value-added service is the main reason for the huge gap. The high-speed development of the machinery manufacturing industry is mainly due to the rapid growth in demand for physical products. With the country's industrialization process in the latter part of the evolution, we should strongly strengthen the modern manufacturing industry.
The industrial development is extensive. The current momentum of the mining machinery industry is in sustained and rapid development, which can not cover up the problem of the extensive mode of development.  In the future, we should put the quality of the products in the first place and transform the development mode.

The Operation and Maintenance for Metal Crusher Machine

The experts of Henan Hongxing Mining Machinery will detailed analyze the operation and maintenance for the metal crusher machine in this article. How to maintain the metal crusher machine?
First, when the metal crusher machine is used for the fixed operations, it should be fixed on the cement foundation. If the workplace is constantly changed, the metal grinder and the motor should be installed on the base made by the angle iron. If the grinder uses the diesel engine as the power, the power of them should be matched. The power of the diesel engine should be slightly larger than the power of the crusher machine and the pulley groove of them should be consistent. The outer end face of the pulley should be on the same plane.
Second, before starting the machine, you should carefully check if the various connecting bolts of the machine unit are tightened, if the tightness of the drive belt is appropriate, if the power cord is good and if the motor shaft and grinder shaft is parallel.
Third, check if the hammer is good and if the bore diameter of the sieve is appropriate. Drag the belt with your hand to check if the rotation of the spindle is flexible.
Forth, after starting the machine, you should make the machine run without load for 2 to 3 minutes to check if the direction of the rotation of the rotor is right and if the sound is normal. The machine can only work at the rated speed.
Fifth, in the working process of the machine, you should pay attention to the operation situation of the crusher machine. The feeding should be uniform to avoid the clogging of the machine. The crusher machine should not work with load for a long time. If there is vibration, noise and high temperature of the machine, you should timely stop the machine and exclude the faults.
Sixth, the materials to be crushed should be carefully checked. There should be no metal blocks, stone blocks and other foreign bodies in the crushing chamber.
Seventh, when the machine is at work, the operators should not leave from the machine unit or disassemble the machine to observe the situation in the crushing chamber.

Overload Protection Measures for the Jaw Crusher

The jaw crusher often works in harsh environment, so the load volatility is relatively large and the peak load is usually more than three times than the average load. In addition, the uneven feeding and the extremely tough non-crushing materials into the crushing cavity will suddenly cause the substantial overload danger. The overload of the jaw crusher will not only increase the attrition degree of the inner parts, but also greatly reduce the service life of the equipment. Seriously, the overload danger may pose a threat to the personal safety of the operating personnel. Therefore, there should be overload protection measures for the jaw crusher. At present, the overload protection measures often used can be divided into the following.
The first is the breaking off of the bracket. You can set the low-intensity and easy break point of the bracket. When the overload of the crusher appears, the stress sensitivity district of the toggle plate will break off because the stress sharply rises to the limit, which can cut off the power transmission to prevent the damage to the machine. The traditional overload protection measure has the advantages of simple structure and easy manufacture. However, since the volatility of the mechanical performance of the bracket is relatively large and it is limited to the calculation accuracy, the control breaking point can not be accurately measured.
The second is the protection of the limit moments for the flywheel. You can use the spring friction clutch, hydraulic friction clutch or the safety pin. Such method is often used for the simple pendulum jaw crusher. This kind of clutch should ensure the transfer of the torque under normal condition. In addition, it should make the torque transferred not be more than the allowable value. When there are foreign bodies falling into the crushing chamber, the overload of the machine will appear, which may reach the critical torque. The flywheel can slide freely on the spindle, which can protect the components of the jaw crusher.
The third way is the hydraulic protection. Since the above two overload protection methods may cause certain accidents, which will not suitable for the needs of the production. Therefore, the development of the safe and reliable hydraulic protection device to replace the traditional means can ensure the stable and continuous operation of the machine.

How to Choose Crusher Machine for Waste Plastics

At present, plastic has become the indispensable production and living supply in the social life. However, the waste plastic produced annually in China is about 500 million tons. The plastic with corrosion-resistance is not easily broken down. Especially the disposable plastic packaging waste and the plastic agricultural film are thrown away, which will cause the white pollution. The potential harm caused by the waste plastic to the environment has become the environmental concern of our community.
With the development of China's scientific and technological progress, the waste plastic processing industry has got very good development. The recycling of the waste plastic is gradually becoming an important project for China's renewable resources and environmental protection. The advanced and efficient crusher machine produced by Henan Hongxing Mining Machinery can make the waste plastic crushed intensively and make it become the renewable material to take full advantage of its intrinsic value, conserve resources and protect the environment. However, in the selection process of grinding equipment for the waste plastic, you should pay attention to the followings.
First, the selection of the crusher machine mainly depends on the type, shape and required crushing degree of the materials to be crushed. The waste plastic with different material should use different crusher machine.
Second, the hard polyvinyl chloride, polystyrene, Plexiglas, phenolic resin, urea resin and the polyester resin are plastics, which are brittle and fragile. Once they suffer from the compression force and the impact force, they are easily to be fractured to be crushed to small pieces. For this kind of plastic, you can use the compression or impact crushing equipment for crushing the materials.
Third, for the ductile plastic which has high ductility at room temperature, such as polyethylene, polypropylene, polyamide, ABS plastic, etc., you can use the shear crushing equipment, because they are difficult to be crushed when they suffer from the external compression, bending, and impact action. In addition, for the elastic material and soft material, you had better use the cryogenic grinding.
Forth, you should determine the crushing equipment according to the crushing extent of the waste plastic.

Introduction to Four Safety Devices of the Jaw Crusher

In this article, the engineers of Henan Hongxing Mining Machinery will introduce four safety devices of the jaw crusher for you.
The first is the hydraulic friction clutch, which is used in the simple pendulum jaw crusher with subparagraph start. The hydraulic friction clutch is installed at both ends of the eccentric shaft. When there is overload phenomenon, the overcurrent relay can start the hydraulic pump motor by delaying the relay so that the clutch can be separated. At the same time, you should cut off the main motor to play the insurance role. 
The second is the overload protection arm device. This kind of device mainly depends on the connection between the pulley and the spindle of the crusher through the leaf spring. The torque can be achieved by adjusting the gasket. When overload occurs, the leaf spring and pulley disengage. The pulley idles on the spindle, while the spindle stops rotation. When the overload is removed, the machine can rapidly reset. The device will not damage any parts. It is safe and reliable with high sensitivity.
The third is the hydraulic rod safety device, which connects with a hydraulic cylinder and piston through the connecting rod. The hydraulic cylinder is connected with the upper part of the connecting rod. The piston is connected with the lower part of the connecting rod. When the device works, the hydraulic cylinder is full of the pressure oil. The piston and hydraulic cylinder are regarded as a part of the overall connecting rod. When the load occurs, the increasing tension on the connecting rod makes the oil pressure in the lower oil room increase. When the oil pressure exceeds the predetermined pressure of the high pressure relief valves of the combining valves, the pressure oil will be discharged through the high pressure relief valves. Therefore, the movable jaw will stop swinging.
The forth is the thrust plate. In the design of the components, the thrust plate is designed to the weakest link. When the overload occurs, the thrust plate will be firstly cut to prevent the other parts of the equipment from being damaged.

How to Determine Efficiency of the Vibrating Screen

The high frequency vibrating screen is composed by the exciter, ore slurry distributor, screen frame, rack, suspension spring, sieve and other components. In addition, the high frequency vibrating screen uses the cylinder-type eccentric shaft exciter and the eccentric block to adjust the amplitude with long drip line of the material sieve and many screening specifications. Well, in the screening process, will the technical and economic indicator, namely the screening efficiency (quality indicators) and productivity (number of indicators) meet the ultimate desired effect of the users? What factors affect the screening of the high frequency vibrating careen?
Compared with the general screening equipment, the high-frequency vibrating sieve uses the high frequency, which can destruct the tension on the surface of the pulp and the high-speed oscillation of the fine materials on the surface of the sieve. In this way, the separation effect of the large-density useful minerals can be accelerated and the contact probability of the materials less than the separation particle with the sieve hole. Therefore, good separation conditions can be formed so that the materials less than the separation size, especially the materials with large ratio can become the products under the sieve with the slurry.
The above description shows that the main factors to affect the high-frequency vibrating screen can be roughly divided into three cases.
The first is the physical properties of the material sieved. The physical properties include the grain composition of the material itself, humidity, mud content and the particle shape. When the fine particles contents of the material are too large, the productivity of the sieve will be large. When the humidity of the materials is large, generally, the screening efficiency will be reduced. If the size of the sieve hole is large, the water effect will be little. Therefore, for the wet materials with large moisture content, you can enlarge the sieve hole to improve the screening process.
The second is the properties and structure parameters of the screen surface. The straight line high frequency vibrating screen makes the particles and the screen surface do vertical movement, so the screening efficiency is high and the production capacity is great.
The third are the production conditions and sieve amplitude. When the load of the sieve is too large, the screening efficiency will be low. Meanwhile, feed uniformity has great significance for the screening process, so the inclination angle of the sieve should be appropriate.

Careful Consideration Is Vital When You Select Crusher

The design of the crushing equipment and milling equipment must be based on the tasks that the crushing equipment and the milling equipment need to complete. In addition, the design changes with the size of the average particle. When the particles become large, the number of particles of unit ore weight relatively reduces, and the energy required to crush each particle should be large. When the particles are small, the number of particles of the unit ore quality is large, and the energy required to crush each particle is small. Thus, generally speaking, the equipment which is adapted to crush the large particles must be unsuitable for crushing the small particles. The jaw crusher and cone crusher are suitable for crushing the rock whose diameter is larger than 3cm. However, the milling machine is adapted to crush the small particles.
Grinding and crushing are inseparable. Therefore, both of them should be used in conjunction. In this way, the concentrate grade and recovery can be improved. The milling process is the energy consumption in the concentrator and it is the largest job for the metal consumption. The investment in equipment also occupies a very high density. Therefore, to improve and increase the indicators of the grinding and grinding operations has great significance for the concentrator, which is also one of the important directions for the mineral processing technology. The crushing equipment is indispensable equipment in the grinding process. Therefore, selecting energy-saving and high-yield crushing equipment is very necessary in the grinding operation. There are a wide variety of ore crushing equipments, but the ideal equipment can be chosen and used is few. As a result, in the selection of the crushing equipment, we must comprehensively consider to choose the best grinding equipment and the crushing equipment. Each crusher has advantages, while there are also the inevitable shortcomings. For example, the consumption of the hammer head and liner in the hammer crusher is very large. The replacement is frequent. The yield is low with high power consumption. In addition, the maintenance is difficult and the equipment operation is low. So, we must choose the best crushing and grinding equipment to improve the production yield.

Impact of Relative Motion of Crushing Cone on Crusher

For the traditional cone crusher, the crusher machine only can be started and stopped when there are no materials in the crushing cavity. If the machine is stopped in the load state, we must thoroughly clean the crushing cavity before restarting the crushing machine. Starting crusher machine with load is absolutely prohibited. In the conventional crusher machine, the connection between the crushing cone and the motor is rigid. In the operation process of the crusher machine, the swinging stroke of the crushing cone keeps unchanged because of the limits of the eccentric sleeves. Therefore, if you start the crusher machine when there are materials in the crushing cavity, the starting torque is required large, which will cause serious damage to the crusher and motor. Too many materials into the crushing cavity will cause the blocking problems of the crusher machine. Therefore, you should install the feeding machine for uniform feeding operations. When non-crushing materials enter the crushing cavity, the crusher machine will be seriously damaged. As a result, the traditional crusher machine needs the overload protection device, which will bring very high costs for the whole crusher machine.
The crusher allows to starting and stopping with load. Since flexible connection is used between the crushing cone and the motor of the crusher, the amplitude of the crushing cone is not subject to the limitations of the transmission system. When the crusher machine starts, the oscillating frequency of the crushing cone is small, the crushing force is also small and the swing angle of the crushing cone is smaller, so the starting torque is also small. As a result, start with a load will not damage the crusher machine. When there are no materials in the crushing cavity, in the running process of the crusher, the crushing cone rolls without gap along the inner surface of the fixed cone, which will cause the mutual attrition between the crushing cone and the fixed cone. This situation should not occur. Therefore, the inertia cone crusher must start with. Staring machine without load is not allowed.

Eight Suggestions for Mining Machinery Factories

With the development of economic construction, the industry has higher and higher demand for the mineral resources. Especially in recent years, the prices of a variety of metal ores skyrocket, which can be described as the second spring of the mining industry. With the high profits of the mining industry, more and more people join the ranks for the mining factories. However, we all know that the high profit is always associated with the high risk. Especially, some of the people who do not understand technology will suffer from great risk. For this, the experts of Henan Hongxing Mining Machinery will put forward suggestions for you in this article.
First, for the mine that you want to invest, you must first know the geological reserves regardless of the grade. You have better have the detailed geological investigation report. For the resources which only had the geological survey, you had better ask the geological experts for best guidance to understand the orebody causes and orebody types to further predict the resource prospects and whether it is necessary to do the geological work.
Second, through the ore beneficiation test, you can well determine the best process, process conditions and optimum process indicators to ensure the qualification of the products and the maximization of the recycling and to provide the basis to reduce the production costs as much as possible for future production. In the early mining stage, the profits have uncertainty. The technology is the primary productive force, so we must attach importance to technology!  The technical inputs can be said is lucrative.
Third, according to the beneficiation test process, the processing amount of ore and the on-site conditions, you can start the plant design and choose the reasonable mineral processing equipment. When you buy the mining equipment, you should choose the equipments with good quality if the price difference is not very large.
Forth, the beneficiation process and technology conditions may be different because of the difference of the grade of the ore, the structure, the mineral and mineral occurrence state.  Fifth, after the concentrator is built, you must ask the beneficiation technology personnel for on-site guidance in the trial production period.
Sixth, the mines safety must be in the first place. Only security can ensure the production. Seventh, solve the environmental pollution, especially the sewage discharge.
Eight, you must do a good job in terms of the mine management.

3D Modeling and Assembly of the Crushing Machine

This article will explore the 3D modeling and assembly of the crushing machine. Let’s take the jaw crusher for an example to analyze the overall structure. The jaw crusher is composed of the frame, movable jaw parts, adjustment parts, transmission parts, taut parts, lubrication components and others. We should achieve the 3D modeling and assembly in accordance with the design requirements for the crusher. The rack is basically composed by the welded steel plate, but the characteristics are many and the shape is complex. When we use the 3D design software for the modeling and assembly, there will be too much work if those welded steel plates are directly built as a single part in the part environment. It is easy to cause the errors and the maintenance is difficult. As a result, we should first create model for the simple steel plate. Then we can assemble the welded parts to the form of assembly.
The key technologies and techniques for the modeling and assembly of the crusher are summarized as follows.
First, you should first create the matrix for the three-dimensional modeling of the parts. Then you can build the rest of the features on the substrate. Based on this, you should classify the parts first of all. The crushing parts are mainly divided into plate parts, cylinder parts and others. The welded steel plate in the rack and the jaw plate are composed by the plate parts. There are many cylinder parts in the movable jaw parts. In most cases, the matrix of the plate parts is created by the extrude feature. The matrix of the cylinder parts matrix is created by using the rotate or stretch characteristics. Of course, this is not stereotyped. We should combine with the specific situations. The scanning and lofting features can be used in the matrix of the parts.
Second, the 3D design software is based on the sketch. In terms of the feature-based 3D design software, the quality of the sketch determines the quality of the part model. Sketches include the geometry and dimensions, geometric constraints. The sketch of crusher parts has completely right geometry.
Third, the overall structure of the crusher is basically symmetrical, so reasonably solving the symmetrical features and parts can improve design efficiency and save time, which also has a vital role for the overall assembly of the crusher and analysis. The parts with symmetrical structure can achieve the direct creation of the symmetrical sketch and can create a half model to achieve this by using the environmental characteristics.

Main Configuration Equipment for Sand Production Line

As we all know, with the social and economic development, the use of quartz sand is more and more widely. Quartz sand is a kind of hard and wear-resistant silicate mineral with stable chemical properties. The unique physical and chemical properties of the quartz sand make it play very important role in aviation, aerospace, electronics, machinery, as well as today's rapid development of IT industry. Therefore, the high-purity quartz sand has a wide range of market, which also creates a huge space for the development for the quartz sand production line equipment.
According to the characteristics of the quartz sand, the requirement for the processing equipment for the quartz sand is higher than the requirements for the processing equipment for other materials, which is determined by the wide application of the quartz itself. Different industries have different requirements for the quality of the quartz sand. How to ensure high-purity quartz sand? Henan Hongxing Mining Machinery Co., Ltd. has strengthened the study on the high-purity quartz sand production line equipment to improve the performance of the equipment, the production efficiency and the service life, etc.. The current high-purity quartz sand production line processing equipment has quite good performance. There are mainly two kinds of the production line configuration, namely the dry type and the wet type.
The first is the dry high purity quartz sand production line. The equipments mainly include the jaw crusher, quartz sand making machine, conveyor belt and the screen equipment. The process flow is that the quartz ore materials should pass the jaw crusher one by one according to the size. Then the materials are crushed to smaller particles. The stone materials are crushed by the quartz sand making machine and screened by the screen. The magnet stick and the exhaust magnet may be used to remove the iron in the screening process.
The second is the wet purity quartz sand production line. The main equipments include the jaw crusher, quartz sand making machine and the waterway system.

Selection of Auxiliary Equipment for the Beneficiation

The crushing machine is very important in the beneficiation. However, the auxiliary equipment also plays very vital role in the beneficiation. Therefore, we must do well in terms of the selection of the auxiliary equipment for the beneficiation.
The auxiliary equipments for the beneficiation mainly include the screening equipment and the belt conveyor. The must select appropriate machines for the beneficiation. This article will explore the selection of the auxiliary equipment for the beneficiation.
Which aspects should you consider in the selection process of the screening equipment?
The first is the sieve mesh. The sieve mesh is required to be uniform and it must meet the standard. The tolerance range should be small, such as 0.10mm ± 0.01mm etc.. Otherwise, the sieve mesh is substandard good.
The second is the screening efficiency. If the number of the sieve mesh is many, the screening efficiency will be high and the yield will be also high.
The third is the connection. There is screen film for the automatic connected device. The connection is easy and timesaving. The disassembly is convenient, which is easy to shorten the working hours and the replacement time by using the initial local sieve. Therefore, the production efficiency is improved. The connection between the sieves is tight without mine leakage.
Forth, the toughness should be moderate. The screen films should have strong rigidness to ensure that there is no break in the production. In addition, the screen firms should also have certain toughness.
The fifth is the hard spot. The distribution of the hard spot is uniform. The hard spots are distributed in diamond-shaped arrangement, which is easy to improve screening efficiency.
The sixth is the appearance. The appearance is fine and the sieve is flat. The hue should be pure without broken bars, glitches, lack of material, mixing or tightly sewn phenomenon.
When you select the belt conveyor, you should follow the following characteristics.
You can choose the belt conveyor with variable direction, which can flexibly change the transport direction. The maximum can reach 180 degrees. Each unit of the conveyor consists of eight rollers. Each unit can be used independently and multiple units can also be used for connections with easy installation.

Lubrication System Design of Hydraulic Cone Crusher

The lubrication station is composed of the fuel tank, fuel pumps, filter (binoculars mesh oil filters and magnetic filter), tube cooler and instrumentation, piping, valves and other components. The oil is sucked out from the tank, which is directly sent to the lubrication points of the device through the check valve, binoculars mesh-type oil filter and cooler. The high work pressure of the oil station is 0.4MPa. The lowest work pressure is 0.1MPa. According to the requirements of the lubrication points, you can determine the using pressure by adjusting the safety valve. When the working pressure of the petrol stations working exceeds the pressure of the settling pressure of the safety valve, the safety valve will automatically open. The excess oil will be back into the tank.
The structural characteristics of the thin oil station are the followings.
First, there is a spare pump. The thin oil station has two oil pumps. The oil pump works in normal circumstances. When the system pressure is lower than the set value, the alternate pump works to ensure to continue supply the host with lubricants.
Second, the binoculars mesh-type oil filter is put in the cooler. The oil passing ability of the oil in the oil filter is related to the viscosity of the oil. If the viscosity is great, the oil passing ability is poor. On the contrary, if the oil passing ability is good and the temperature is high, the viscosity will reduce. The good oil passing ability will cause good filtering effect.
Third, you can use the binoculars mesh-type oil filter. The binoculars mesh-type oil filter has two groups of filter elements. When the working filter element needs to be replaced, you can use the switching valve to make the spare filter element work. You can remove the original filter and replace the filter disc. This kind of oil filter has compact structure, which is easy to be replaced.
In a summary, the crushing machine requires scientific and technological innovation. The mining enterprises should design and produce the crusher according to the market demand. The hydraulic cone crusher can greatly improve the crushing efficiency of the crusher itself and reduce the labor density.

Analysis of Design and Calculation of Impact Crusher

Theoretically, the yield of the coarse impact crusher can be calculated according to the crushing materials produced through one circle of the rotation of moving cone. In fact, the amount of the discharging material in the unit time not only relates to the size of the circle, but also relates to the density degree of the material. Obviously, this assumption does not fully reflect the actual situation. To this end, in the actual production, we usually use some empirical formula for calculation. The crushing process of the impact crusher is similar to the crushing process of the jaw crusher. Therefore, the calculation method of the jaw crusher still can be used in the calculation process of the coarse impact crusher. The derivation method of power needed by the coarse impact crusher in the theory is basically similar to that of the jaw crusher.
At present, the domestic calculation for the strength, rigidity, abrasion resistance, and the stability of the main components of the impact crusher is not perfect yet. Therefore, in the design calculations, we should still use the design methods of the heavy machinery and general machinery parts to do the design calculations of the impact crusher. There are major three parts for the design and calculation of the impact crusher. This parameter is the structural parameter required by the process of the impact crusher. The ores are fed into the impact crusher through the conveyor belt. The ores through the ore dividing plate do not directly fall in the ore mouth. Therefore, the circle space formed by the ore dividing plate and the fixed cone should not be stuck by the large pieces of the ore. The cone angle of the material hopper should be determined by the liner of the moving cone.

Analysis about the Hongxing Calcining Rotary Kiln

The flexible driving with multichannel engaging has a variety of forms. According to the features of the calcining rotary kiln, we can use the dolly flexible driving with multichannel engaging when we transform the driving device. The temperature intelligent monitoring system of the rotary kiln is the core technical aspect in the new generation of dry cement production process. Since the rotary kiln has the features of nonlinearity, multi variables, strong coupling, the kiln situation of the rotary kiln is ery complex. The control is also extremely difficult. If the temperature is too low which leads to the inadequately combustion of the fuels, the energy waste and environmental pollution will be caused. If the temperature is too high, it will make the production of raw materials calcined excessively, which will also affect the quality of the products.
IPC, PLC and Porfibus-DP fieldbus solutions are used in the overall design of the monitoring system. The system can be divided into three layers, namely the live execution layer, a layer of intermediate control, the layer of system monitoring. In the system design, the kiln firing system is a difficulty of control as a multi-variable nonlinear coupled system. Through the analysis of its characteristics, the experts of Henan Hongxing Mining Machinery have put forward the production rules in accordance with the degree of autonomy, the principle of compensation combining with the artificial experiences as well as the advantages of the PID control algorithm. In addition, we use the feedforward compensation in the loop for the major disturbance factors to compose the feedforward and feedback control system programs. The kiln belongs to the large delay and nonlinear time-varying object. FUZZY-PID control algorithm is used in the temperature control loop to design the parameters from the FUZZY-PID controller tuning and FUZZY optimization controller to achieve the optimization of the system control. The simulation results show the effectiveness of the control algorithm project.
The users of the rotary kiln should summarize the experience as much as possible and recognize the situation of the rotary kiln through the advanced intelligent control theory.

Power Consumption and Rotating Numbers of Jaw Crusher

In the crushing process, the power consumption of the jaw crusher is related to the number of revolutions, standard size, the size of the discharge opening, nip angle, particle size characteristics and the physical and mechanical properties of the materials to be broken. Among the factors, the physical and mechanical properties of the materials to be crushed have the greatest impact on the power consumption of the crushing equipment. Of course, if the specifications size of the crushing equipment is large, the power consumption will be great. If the number of revolutions of the eccentric shaft increases and the crushing ratio increases, the power consumption will also increase. Since there are a lot of factors affect the power consumption of the jaw crusher, there has been no complete theoretical formula to be used to calculate the power consumption of the crusher.
In the parameters optimization design of the institutions size of the jaw crusher, the power of the jaw crusher is an important constraint condition. As a result, we must establish the calculation formula of the power of the crushing machine. The derivation of the power of the calculation formula of the jaw crusher should be in the crushing process with cycle of motion. It should be based on the work of the crushing force in the displacement direction of the points of the teeth surface. In order to facilitate the calculation, it is assumed that all points on the tooth surface of the moving jaw move parallel according to its average value of its horizontal in the crushing process without taking into account the friction between the material and liner. Regardless the distribution of the crushing force on the liner and the change and size of the crushing force on the liner of the moving jaw, a concentrating force which is perpendicular to the tooth surface of the moving jaw is set. The work done by the concentrating force along the average horizontal throw in the movement circle and the actual crushing force along the actual horizontal throw on the tooth surface of the moving jaw are equivalent.

Single Cylinder Hydraulic Structure of Impact Crusher

The impact crusher has the characteristics of large crushing ratio, high efficiency, low power consumption and uniform particle size. The impact breaker is suitable for crushing hard materials, so it is still widely used in the world. The experts of Henan Hongxing Mining Machinery have transformed the impact crusher with the hydraulic device to make the impact crusher become more complete.
The impact crusher has a swinging angle which is 4 times larger than the swinging angle of the jaw crusher. In addition, the impact crusher has the rotating speed which is 2.5 times higher than the rotating speed of the jaw crusher. In such high-speed and large-stroke crushing process, the materials suffer from large-stroke impact unlike the slow-speed and small-stroke impact in the jaw crusher. This kind of impact crushing method is conducive to crushing the material. Therefore, the crushing efficiency is high. Due to the high speed and large stroke of the impact crusher, 95% materials in the crushing cavity are in the decline state of motion along the cone. It is means that only 5% materials are in the crushing state at any moment. Since 95% materials are in the decline state, the passing capacity in the crushing cavity is large and the output will be greatly improved. Since only 5% materials are in the crushing state, there is only 5% area in the whole crushing cavity us used for crushing materials. As a result, the energy consumption is low. Further, in a partial area of the crushing chamber, very high pressure will be produced for the materials per unit area, which makes the impact crusher is suitable for crushing hard ore.
The parallel zones with different lengths are set in the lower part of the crushing capacity and the rotating speed is high, which can ensure that the materials can be crushed once at least in the parallel zone. Therefore, the particle size of the materials crushed by the impact crusher is uniform. The impact crusher can be used for medium crushing and fine crushing. The difference between the medium crushing and the fine crushing lies in the difference of the shape and the size of the crushing cavity. The other structural principles are exactly the same.
