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.

The Types and Future Development of the Jaw Crusher

The jaw crusher appeared in 1806 and it was an old crushing equipment. However, due to its simple structure, compact structure, lightweight, easy manufacture, reliable work and the small overcrushing phenomenon, as a result, the jaw breaker is still widely used in coal dressing, metallurgy sintering, cement, glass, ceramics and other industrial sectors, as well as the small concentrators. In recent years, the jaw crusher has very great development and progress.
The jaw crusher is widely used for crushing soft and medium hardness materials. The range of applications of the jaw crusher is larger than other crushing machines in terms of crushing the wet material and viscous materials. However, since the jaw crusher can not be used for crushing the large pieces of material and hard material, the using range has been limited. In recent years, the jaw crusher at abroad develops quickly. There are many types of jaw crusher and the specifications are relatively complete.
According to the numbers of the rollers, the jaw crusher can be divided into the single roll crusher, double roll crusher, three-roll crusher and four-roll crusher. According to the shape of the surface of the roller, the jaw crusher can be divided into the smooth roller jaw crusher, toothed roller jaw crusher and trough roller jaw crusher. In terms of the structure of the jaw crusher, the automatic mobile roller mechanism, hydraulic adjustment, oil and gas control system and other new technologies are often used in the modern jaw crusher. However, the structural form and the control system in different manufacturers are different. They have their own unique characteristics.
The jaw crusher produced by Henan Hongxing Mining Machinery uses the rubber tires transmission and the hydraulic adjustment mechanism to automatically position the roller bearings. The operation is smooth and the service life is longer than that of the traditional jaw crusher. The jaw crusher produced by Henan Hongxing Mining Machinery can smoothly complete the coarse crushing and the final crushing. The crushing efficiency is very high. Henan Hongxing Mining Machinery has many years’ experience in terms of the production of jaw crusher. We will provide the most professional jaw crusher for every customer.

Parameter Selection and Calculation of Impact Crusher

The impact crusher is essentially composed of the overlap of two double roll crushers with the same specifications. This article will talk about the structure of the 900 × 700 impact breaker. In terms of the structure of the roller and the spring safety device, there is no difference between the impact crusher and the roll crusher. However, the roller shaft of the impact crusher is supported at the automatic aligning sliding bearing. The transmission means of the impact crusher is composed by two motors, two reducers and two sets of pulleys dirve.
The motor drives the rotation of the rollers by the reducer and the coupling. One of the motors drives the rotation of the roller at the top right, while the other motor drives the rotation of the roller at the bottom left. The other end of the spindle of each roller is equipped with a pulley. The pulley of the right upper roller drives the pulley of the right lower roller so that the right upper roller rotates. The lower left roller pulley drives the pulley of the upper left roller so that the upper left roller can rotate. Since the travel direction of the movable bearing is perpendicular to the travel direction of the belt dirve, the variation of the tensile force is not large when the movable bearing moves. After the materials are crushed by the upper and lower rollers, they are discharged out of the machine from the lower part. There are two sets of cutting device which is made of the turning roll skin. When there are grooves and scallops on the surface of the roller after is worn, you do not need dismantle the roll skin, because you can directly use the cutting device to trim the roller by using the cutting device to ensure the smoothness of the surface of the roll skin surface and reduce the number of stop time to improve the operation rate of the machine.
The main parameters of the impact crusher include the nip angle, feed particle size, roller diameter, the number of revolutions of the roller, the productivity and the motor power and so on. We can use the above parameters to calculate the nip angle. In order to simplify the calculation, we can assume the materials block is spherical. In this way, we can reasonably calculate the parameters of the crusher to improve the working efficiency.
