Deep Study about Medium Filling Rate of Ball Mill


In order to improve the yield of the ball mill, we should not only focus on the technological factors and mechanical factors, but also ensure the effective management and control of the ball mill. The main purpose of the management is to prevent the abnormal operation situation of the machine to achieve the fine operation, low consumption and high yield of the equipment. For the medium movement of the ball mill, the medium filling rate and the rotational speed are two very important factors. In terms the impact of the two factors on the ball mill, many scholars at home and abroad have done a lot of researches about the factors and they have got some conclusions. However, these conclusions are almost based on certain test and the formula calculation. This article will explore the impact produced by these two factors on the ball mill by using discrete element numerical simulation method.
In fact, the media filling rate and the rotational speed of the ball mill together impact the ball mill. If we only analyze one of the factors, the results obtained are only one-sided. As a result, we should combine the two factors. In this way, we can get reasonable analysis results, which can be proved in the future analysis calculation.
The critical speed of the ball mil refers the instantaneous speed. In the changing process of the cylinder of the mill from slow to fast, the medium in the outermost layer of the mill does uniform circular motion with the inner wall of the liner of cylinder. The medium moves to the highest point but not falls down. When the mill is in the critical speed, the grinding media and the grinding materials in the outermost layer rotate with the mill. There is almost no relative impact. The critical speed of the mill is often regarded as a reference standard for the suitable rotational sped and the actual working rotational speed in the research of the ball mill. The domestic and foreign experts have done a lot of research work and the formulas are also numerous. The grinding media can be divided into dynamic and static, so the grinding media filling ratio is also can be divided into dynamic and static.

System Module and Electrical Principle of Rotary Kiln


The direct current governor system of the rotary kiln uses the PID speed control system and regards the three-phase bridge controlled rectifier circuit as the drag system. In the site, the given value can be provided by the PCL. It directly uses the double-loop control system, which achieves the continuous speed. The speed ranges from 0 rev/min to 150 rev/min. The normal operation is from 1rev/min to 1.5 rev/min. The motor and the electromagnetic vibrating feeder use the frequency control. The frequency control is the stepless speed regulation for the alternating current machine so that the speed of the feeding hoist and the electromagnetic vibrating feeder is continuously adjustable. It adopts the PLC control to achieve the automatic feeding control and the adjustment control of the cooler to the electromagnetic vibrating feeder. The hardware of the control system reduces and the remote automatic control can be achieved.
In the fan electrical control system, the on-off control of every fan is achieved by using the PCL. Compared with the previous relay control mode, it can reduce a lot of hard wire to improve the safety of manual operation so that the operation of the fan can match to the actual working conditions to complete the processing requirements of active lime rotary kiln. There are end fan, primary fan and the secondary fan. The adjustment of the air door of the inlet of the primary fan and the secondary fan can be based on the pressure of the kiln end to adjust the air door of the inlet. We can achieve to the adjustment according to the opening regulation of the fluid coupling and the adjustment of the blast furnace, coke oven gas and combustion air mixing proportion and the adjustment of the cold air distribution valve of the preheater. In addition, you can monitor the running state of the fan, motor and other motors through the upper computer and adopt the overload protection.
The temperature automatic control system of the rotary kiln can be achieved through the PLC program, which cancels the previous tone table control mode and has greatly improved the degree of automation and control system accuracy. The temperature of the rotary kiln is controlled by the proportion of the gas and the ventilation rate.

Detection of Slip Fault of the Belt Conveyor


The working environment and working conditions of the mining belt conveyor are quite complex and harsh, which is prone to all sorts of unexpected incidents. How to guarantee the normal work of the belt conveyor and reduce the accidents? Once there is an accident, we must discover and give the repair to improve efficiency and reduce losses, which has become a problem in front of the designers. This article will analyze the common causes of failure and detection methods for the mining belt conveyor.
The working principles of the skid protection system are the followings. The skid protection system uses the sensors to measure the belt speed and the speed of the driving drum. Then the belt speed and the speed of the driving drum are compared.  In normal operation, there is no difference between the two kinds of speed. Therefore, there is no output. If the skidding occurs, there is difference and output. We must delay to protect the machine. We may also use a sensor to detect the belt speed. The belt conveyor can be protected when the belt speed is more than its normal value or below the normal speed. The latter uses fewer elements and the lines are simpler, but the reliability is lower. Therefore, we had better use the former method. The use of the speed sensor to detect the speed of the belt conveyor can achieve the speeding slip protection.
The common speed sensors mainly include the followings. First, the sx-1 type sensor is a magnetoresistive sensor, which is mainly composed by the permanent magnet and a coil wound thereon. It has been made of explosion-proof type. Second, the magnetic sensor is mainly composed by the permanent magnet and multi-toothed wheel and the coil. When the permanent magnet multi-toothed wheel installed on the shaft rotates in the coil, it will produce induced electric potential due to the cutting magnetic line of force in the coil. The frequency of the output pulse signal in the coil is directly proportional to the number of teeth and the belt speed of the multi-toothed wheel. Third, the magnetic induction transmitter essentially is a reluctance type sensor. It consists of a permanent magnet and a coil, etc. The output voltage is 2V to 6V and the current is approximately 2MA.

Attrition of Parts Reduces Service Life of Crushers


The pulverization is an indispensable technical process in the mineral processing. The task of the pulverization is to provide the raw materials for processing with a certain particle size, size distribution, adequate dissociation and unduly pulverization to make the next step of processing, handling and use become easy. The crushing operation (including crushing and grinding) is an essential link in the contemporary rapid development of industrial technology. In a variety of processing procedures of metals, non-metallic, chemical, mineral raw materials and construction materials, the crushing operations need to consume a lot of energy. Especially with the increase in the amount of low-grade ore mined and environmental need to deal with the increase in the amount of waste recycled energy, the energy consumption will also gradually increases. It is expected that the energy consumption which is used in crushing process may be up to 15%. With the development of the society and the continuous consumption of raw materials, the high-grade ore resources are depleted and the proportion of lean ore resource extraction increases.
 The crushing operation is the leader of the ore beneficiation and it is also the operation which has high energy consumption and high consumption of metallic materials. Therefore, the efficient, energy-conservation crushing machinery will play an increasingly important role. The liner is a kind of important wear part of the crusher. In the working process, the liner should withstand certain impact and wear in the course of the work. Material wear is a procedure in which the shape, size, structure and properties change due to the effect of the relative motion, the media, the temperature and the environment. The abrasive wear is a kind of attrition which is caused by the migration or falling off of the surface material due to the effect of the hard protuberance material in the friction process.
The attrition is caused by friction. It is a common phenomenon in the various fields of the national economy and daily life and it is an important factor to cause the loss of materials and energy. In the field of mining, building materials industry, electric power industry, machinery industry, agricultural machinery, defense industry, aviation and aerospace, friction is everywhere and the attrition is also everywhere. The wear is a widespread phenomenon, but its causes and manifestations are very complex. Therefore, we should research and analyse the using situation and the wear mechanism to create the best working condition of the crusher.

The Domestic Production Status of Mechanisms Sand


The quality of the mechanisms sand largely depends on the physical properties of the parent rock, processing, machinery equipment and other factors. The main raw materials for the production of the mechanisms sand include the limestone, dolomite, granite and basalt.
The domestic sand and stone plant is mainly the small gravel plant with less than 50t / h and the production process is simple. The production output of the gravel plants with certain scale is 100t/h to of 200t / h. The two-stage crushing and sieve are mainly used to constitute a closed process job. At present, the problems existing in the mechanism sand industry in China are the followings.
First, there are no professional design concepts and the equipment selection is irrational. The production technology is backward and the production scale is small. In addition, the production of the mechanism sand has serious damage to the environment.
The modern sand production process and equipment of the mechanism is established on the full grasp of the characteristics of the rock material properties and performance of the terminal products to select the appropriate production equipment with organic combination, clear division of labor and mutual matching. However, the production status of mechanisms sand in China is not going well. On one hand, we are lack of professional sand production designer. Most of the researches focus on the characteristics of the mechanism sand and preparation and performance of the mechanisms sand concrete. Therefore, the research of the preparation technology, equipment, process of the mechanism sand is neglected. On the other hand, the production operators think that the sand, stone production technology is simple without professional design. Furthermore, some equipment manufacturers ballyhoo and promote some simple crushing and screening equipment to the market with new names, which is bond to cause of the disqualification of the mechanism sand. The use of the singe-stage jaw breaker and small hammer sand maker goes against the production of the mechanism sand.  
Second, the technological literacy is low and the quality awareness is poor withconfused management.
Most of the practitioners in domestic sand and stone industry has no technical training and their technical literacy is low. They do not how to use and maintain the advanced equipment and process. At the same time, they are lack of the understanding and knowledge of the mechanisms sand technology requirements and they have no concepts of gradation, fineness modulus, the powder content and clay content.

A Brief Introduction to the Ultrafine Wet Crusher


The enclosure of the main body of the ultrafine crusher is equipped with the rotary spindle which is driven by the mechanical rotation and a number of countershafts. There are dozens of ring crushing media in each countershaft, namely, crushing ring. The crushing ring can be freely dismantled, which makes the disassembly and assembly become very easy. The size of the crushing ring is different with the different forms of the device. The outer diameter is in the range from 25mm to 45mm and the thickness is in the range of a few millimeters. Usually there is a gap of several millimeters between the inner diameter of the crushing ring and the outer diameter of the minor axis so that each crushing ring can freely move. There is jacket outside the wall of the crushing chamber. The cooling water can be led into the cement mill to control the temperature rise of the materials. The inner wall of the crushing chamber and the crushing ring can be made of stainless steel, ceramics, or other superhard materials.
When the spindle rotates, the crushing ring moves with the countershafts to produce the centrifugal force. In this case, the gap between the crushing ring and the countershaft moves along the radial direction. The crushing ring strongly presses the inner wall of the crushing chamber. The friction between the crushing ring and the countershaft makes the crushing rotation motion on the countershaft. The materials are nipped by the rotating crushing ring and the vessel wall after the materials enter the crushing chamber. Under the action of centrifugal force and the rotating frictional force, the particles of different sizes in the cavity are crushed and dispersed. Due to the high-speed operation of the crushing ring, satisfactory results can be achieved for crushing and processing the materials with different viscosity levels.
The ultrafine wet crusher is suitable for crushing the slurry with various concentrations and it can easily crush the fibrous material and crush the the layered materials, such as the graphite, talc, etc..
The maintenance of the ultrafine wet crusher is easy. In addition, this kind of crusher has the high-strength shear and compression forces, which can mix, crush and disperse the materials with high viscosity.

The Scientific Management of Hongxing Hammer Crusher


The hammer crusher is a kind of crushing equipment with high-speed rotation. The strong impact requires that the balance between the rotors of the crusher must be fully guaranteed, which can be achieved by strict processing, use and scientific management. Therefore, the first step is the processing accuracy of the parts of rotor. The parts of rotors can be assembled when the static equilibrium or balancing test are qualified. The operation of the installed equipment should be smooth in the early use and the equipment should be safe and reliable to reach the operation rate which has been set. Moreover, after a period of use, even in the long-term use, the reliability should also reach or remain at or above this level. Therefore, in the long-term use, with the anabatic wear of the hammerhead, the yield will reduce and the crushing particle size will become coarse. At this time, you should timely adjust or replace the hammerhead. The serious damage to the rotor balance will inevitably lead to reduction of the using effects and increase of the vibration and noise. The vibration may even cause unsafe incidents. Hence, the balance test should be done again in order to re-use.
The gap between the surface in the screen of the grid section and the surface of the hammer head will have a great impact on the size and output of the product. In the running process of the crusher, this gap should usually remain in the range of 10 to 20 mm which may be appropriately enlarged depending on production needs. After the attrition of the hammerhead and the grid section, the adjustment mechanism can be used to adjust the gap to control the uniformity of the product particle size.
The correct operation and maintenance of hammer crusher should follow the following points. First, you should carefully check the lubrication of the all parts of crusher before starting the machine. Check if the oil is adequacy and if the oil seal is reliable. Second, fasten the various parts. Check if there are sundries in the crusher, especially the iron pieces. Check if the tube is smooth. Third, check if the rotation of the rotor is correct (especially the irreversible hammer crusher). Check if the electrical meter is intact and if the safety protection devices are installed. When the above are normal and correct, you can start the machine according to the following order, namely, the discharge conveyor device, crusher, the feeding device, the feeding conveyor device of the materials to be crusher.
You should periodically check if the production equipment is properly maintained. It is the necessary process to improve the operation rate and extend the service life of equipment.

Analysis about Failure and Common Program of Crusher


If we want to improve the efficiency and reduce the production cost of the jaw crusher and mobile crusher, we have to carefully analysize the causes of the failure of the crushing machine. The purpose of failure analysis not only lies in the discrimination of the nature of the faults and the causes of the malfunction. The most important is to clearly identify the failure mechanism and propose effective improvements to prevent recurrence of the failure. After the failure analysis, we should find the real reason of failure and take measures to improve the reliability of the machine in terms of design, material selection, manufacturing, assembly, adjustment, use and maintenance. Failure Analysis is a multidisciplinary involving many technical fields, such as: system analysis, structural analysis, materials physics, test analysis, as well as related fatigue, fracture, wear, corrosion and knowledge of other disciplines.
This article will briefly introduce the analysis procedures and methods for the cause of the fault. Although the parts and components with the failure vary and the analysis methods and steps also vary, the basic procedures of the failure analysis are common.
The common procedures for the analysis of the failure of the machine are generally the followings.
First, collect background data and conditions of use. The main contents include the date and time of component failure, operating temperature and environment, the extent of the damage to components, the order of the occurence of component failure, the operation stage of the failure, abnormal or unusual sound of the fault parts, photographs or sketches for faulty components and their vicinities parts, any errors which may lead to the failures in the use, the skill level and view of the failure of the users
Second, we should know the focus of the camera for the fault-site. You should take pictures as soon as possible for the things that may be possible to quickly change. The things that may be possible to quickly change include equipment, the instrumented readings and the location of the control, those evidences which can be removed by the weather, pedestrians, vehicles or cleaning staffs, such as the traces on the ground, heated evidence, liquid and so on.
Third, we should know the main historical information of the failure pieces. The historical information Includes part names, marks, manufacturing number, manufacturers, using unit, the function of the components, the materials used, the relevant project, the using time until the failure, design drawings, manual, the guidance component production, manufacturing, testing and operating specifications. When a failure analysis has been done, we should conclude all the information, the survey records, testimony and test data that we have obtained. In this way, we can better improve our work.

A Detailed Analysis of Crushing Force of Cone Crusher


Crushing force is an approximate concept which is used to describe the ability for crushing materials of the crushers. The crushing force is one of the most important basic parameters of the crusher. In the crushing process, the crushing force will be constrained by many factors, such as the different sizes of the material particles, the different hardness of the material, the uneven distribution of the material in crushing cavity, the strong vibration and ruleless change of the movement of movable cone. The mathematical model is difficult to establish. Currently, the crushing force of the spring cone crusher is calculated according to the spring pressure. The crushing force of the cone crusher and hydraulic cone crusher can be indirectly calculated by the available pressure generated by the hydraulic pressure of the hydraulic cylinder.
The main frame of the cone crusher can be divided into upper frame body and the lower frame body. The upper frame body and lower frame body are connected by the hydraulic cylinder group. The role of the hydraulic cylinder group is to provide an initial pressure to overcome the crushing force when the crusher is in normal working condition or the crusher has crushing material load. When non-crushing materials in crushing cavity go through, the crushing force will increase sharply. At this time, the pressure of the hydraulic cylinder can not over the crushing force in a sharp increase. The support ring, the adjustment ring and the liner of the fixed cone will slightly cock. At this time, you can rotate around the strong point on the flange on the frame body flange to a given angle. You can keep rotating until the size of the discharge port increases enough to make the non-crushing material go through. The dynamic cone will be born great crushing force and the pressure of the hydraulic cylinder group will maximize. Because of this characteristics of the cone crusher, the normal crushing force and maximum crushing force of the cone crusher must be determined.

Disposal Status and New Model of Construction Waste


Over time, cycle and reuse career of the domestic construction waste is gradually on the right track. Lots of local governments have introduced policies to support the steady development of the industry. However, there are still problems about domestic construction waste disposal.
First, construction waste is treated, but the consumptive venues are still insufficient.
One hand, daily processing amount needs to be up to at least thousands of tons, but making bricks or plates is very difficult to consume such a large amount of construction waste. On the other hand, even if the deep processing of construction waste is not be affected, conservation and storage of finished goods need a lot of venues, which is likely to cause the backlog of the products the production halts. The digestion ability of the treatment plant will be severely disrupted.
Second, the facilities are outdated which can not be used for classified processing.
Let’s take the construction waste brick-making factory for an example, the fixed crushing equipment is mainly used. Therefore, the construction waste can not be classified so that the brick products made of raw material with different quality are different in weight, strength and quality.
Third, the construction waste will cause secondary pollution for the environmental programmes.We should avoid the pollution of the construction waste in terms of in terms of noise, dust and soot.
Forth, the fixed crushing equipment is used which cause transhipment charges of thegarbage. It is understood that the storage of the construction wastes in the building waste treatment plants occupy about half of the area of plant.
For the above reasons, the construction waste treatment plants have turned to the exploration of the new model. They mainly use the environmentally advanced mobile crushing station. The device can effectively solve the above problems. The range of the application of the mobile crusher will increase, which is mainly used for municipal, highway and construction industry.
Most construction waste treatment plants exit as a "material supply base" model. The construction waste should be classified at first, and then it can be used for municipal road and highway construction, such as cement stabilized layer processing, sidewalks grassroots, backfilling of the pipe pit and soft ground treatment. This processing mode not only creates considerable economic benefits for many companies, but also brings excellent social effects.

Cone Crusher Improves Crushing Efficiency of Iron Ore


The crushing process of the iron ore generally uses the feeder, primary crushing, two-stage crushing, screening, fine crushing and dry separation process. In order to improve the efficiency, the particle size of the iron ore into the dry separator should be as fine as possible. Therefore, we should greatly imrove the crushing efficiency of the iron ore. At present, a large number of individual domestic beneficiation units still use the traditional hammer crusher, which is a kind of investment mode with the lowest cost, but the production efficiency is very low. Some small concentrators directly use the iron ore crushed by the fine jaw crusher for dry separation, which has caused serious waste of natural resources. As we all know, the jaw crusher is generally used for the primary crushing of iron ore production operations. At present, the domestic manufacturing process and technical level of cone crusher has been very mature. If you select the jaw crusher produced by the regular factories, the design and production requirements can be met.
The cone crusher or fine jaw crusher is often used for secondary crushing. The fine jaw crusher is generally used for the separation of the small pieces of iron ore. The structure is simple and the maintenance is easy. However, the discharge opening of the fine jaw crusher can only be adjusted to 25mm, so the crushing particle size is generally less than 40mm. The structure of the cone crusher is more complex with high value. However, its production is large and the crushing granularity is fine. The wearable pieces have long service life. Therefore, the cone crusher is heavily used in the large-scale iron ore separation plants.
The cone crusher (iron ore crusher) produced by Henan Hongxing Mining Machinery is based on the introduction of the advanced technology of the American Symons cone crusher. Hongxing Mining Machinery also combiles many years' practice to produce this kind of cone crusher. In the crushing process of the iron ore, the production capacity, product size, product shape, the weight, maintenance and operation of the cone crusher are superior to iron ore crusher.
In terms of the efficiency and cost of iron ore, using the cone crusher produced by Henan Hongxing Mining Machinery can effectively reduce the production cost, because the cone crusher can provide smaller granularity. The production practice of a number of iron ore mining plants has proved that the cone crusher produced by Henan Hongxing Mining Machinery is the most economical mode for the crushing task of iron ore.
