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.
