Hongxing Sand Maker Is Best Choice among Crushers

According to the analysis of the current building, regardless of road and bridge construction or high-speed and high-speed railway construction, the sand and gravel aggregates are the most basic and the most widely raw materials. The building sand has received special attention because of the draw materials and the properties of the sand and gravel aggregates. How to choose good aggregate production equipment has become a top priority for a lot of investors and the aggregate manufacturers. The modern impact sand making machine can produce the mechanism sand with good quality, which can solute the environment pollution of the sand making industry and can improve the utilization of the resource. In addition, the sand making machine produced by Henan Hongxing Mining Machinery can bring a lot of benefits for the gravel plant with fierce competition to become the comprehensive interest. At abroad, the advanced countries have many years’ for the study on the use of the sand making machine. The processing equipment in our country can basically meet the requirement of the sand making industry. The developing conditions of the sand making machine have been mature and imperative.
The impact sand making machine produced by Henan Hongxing Mining Machinery has been improved from the technology. The inner structure uses the impact hammer and the impact liner. The operation is simple, which can achieve the beat crushing type and the impact crushing type. The grain shape of the sand and aggregate is good. The ores processed by the impact sand making machine has the good grain shape. The sheet rate of the some stones with small bore diameter can be up to 100%. In the traditional production process of the sand and aggregate, the stone are sent to the jaw crusher for primary after they are crushed through blasting. Then you can choose the impact crusher for medium crushing according to the hardness and the yield of the stone. At last, the stone are crushed by the sand making machine to standard particles. The wet-type sand making machine also requires the cleaning process for the sand and aggregates.

3D Design Software Is Used in the Crusher Industry

In this article, the experts of Henan Hongxing Mining Machinery will mainly introduce the train of thought for the computer-aided 3D design of the crusher machine, which is mainly about the key technology and skill of the 3D solid modeling assembly, parametric design, strength, rigidity checking, interference collision check and movement simulation in software environment. In recent years, we can make the structure of every part, the assembly relationship of every layer and the various movement trajectories become clean through the 3D solid model and the operation simulation built in the crusher by the 3D design software. The parameters can be shown visually, which can bring more emotional understanding for the designers. In addition, the parameterization functions of the 3D design software parameters can provide convenience for the improvement and modifications for the future products. It is can be said that the use of computer-aided three-dimensional design for the crusher can achieve the dual purpose of improving the design efficiency and quality.
With China's sustained economic development, China's iron and steel industry and mining has been developing rapidly. The social demand and the production scale of all kinds of metal, non-metallic, chemical, mineral and other materials gradually increase. The amount of the materials which need crushing increases rapidly. Therefore, the demand for the crusher machine becomes larger and larger. The design and development of the crushers with various specifications is closely related with the development of construction, high-grade highways, bridges, dams and mining. The using range of the crusher is increasingly wide. The commonly used crushers include the jaw crusher, cone crusher and so on.
The 3D design software is based on the feature parameterization 3D solid modeling system. Before the start of the design, the software can consider the overall structure and then formulate the good design lines to effectively perform the function of the system, shorten the design cycle and improve design efficiency.
There are two ways by using the 3D software design. The first is the down-top design. This way is relatively traditional. You should design the parts in advance and then insert the parts into an assembly. In this way, the parts are designed independently. The second way is top-down design, which can improve the design efficiency.

Accessories Quality Is Judging Standard for Crusher

People often put the accessories of crusher machine in a relatively minor position from the literal meaning. Most people think that the accessory of the crusher machine is only the supporting role in the day-to-day production of the crusher. This understanding is one-sided, which confuses the very important position of the accessories of the crusher machine in the crushing production.
For example, if we regard the crusher machine as a person, the accessories of the crusher machine are the parts of the human body. The accessories are small but complete. The importance of the accessories for the crushing machine is obvious. In fact, the crusher accessory is customary title in the mining industry.
In the day-to-day production of the crushing machine, the cost of the crusher parts far higher than the maintenance costs. Let’s take the hammer crusher for an example. The hammerhead of a DPC1412 single-segment hammer crusher needs to use 28 hammerhead of the crusher. Each hammerhead is 52kg and the full set of hammerhead weighs 1456kg. Usually, we should replace the hammerhead every two weeks. The price of the hammerhead of the hammer crusher is calculated through the weight. We can find that the quality and the replacement cycle of the accessories of the hammer crusher has a direct impact on the crushing machine.
However, compared with the host device of the crushing machine, the accessories of the crusher machine develop slightly slow at home, especially the jaw plate of the jaw crusher, the rolling mortar wall of the crusher and the impact plate and the plate hammer of the crushing machine in the small and medium-sized mines. Due to the poor working conditions and the strong abradability of the materials, part of the accessories of the crushing machine may break. In addition, the performance of the products is not stable. The instability of the accessories of the crushing machine may seriously limit the development of the crushing industry. In this case, the upgrade of the accessories of the crushing machine becomes particularly important.
China will continue to increase energy saving, emission reduction, and the use of intelligence and information to improve the reliability of the products as development priorities and the central task of the mining machinery industry in the future. Therefore, the quality of the accessories of the crushing machine becomes the new standards to judge the performance of the crusher machine.

Four Points to Improve Yield of Sand production Line

In the running process of the sand production line, many companies want to improve the yield of the sand making machine. However, many enterprises have ignored the performance of the sand making machine itself. If we want to get the high yield of the sand making machine, we must have a deep understanding about the factors which affect the production capacity of the sand making machine. Only we improve the affecting factors of the sand making machine can we improve the yield of the sand making machine in the sand production line. The experts of Henan Hongxing Mining Machinery will analyze the four factors that affect the production capacity of the sand making machine in the sand production line. 
First, for the settings of the feeding device of the sand making machine, we must adopt the unified specification process so that the granulocyte level difference can be reduced to minimum extent in the feed. The sand making machine can run with high speed under such conditions. However, with the increase of the inertial force, the operation will reach relatively high fluency.
Second, in the selection process of the cavity shape of the crushing cavity of the sand making machine, we fine that not narrow space can make the materials resident in the warehouse for a long time, which can promote the effective work of the sand making machine. However, we should determine the time by contrasting the time consumption in the whole work flow. Usually in the case of low yield, the experts for the sand making production line remind customers can choose 2 or 3 cavity design. If it is in the case of high yield, it is necessary to use the even chamber even a cavity design to meet the requirements. The regulation is also important for the sand making machine in the sand production line. Reasonable regulation is conducive to the enhancement of the performance.
Third, for the cavity design of the sand making machine, one- cavity structure design is simple. We can control the granular level of the materials very well with this kind of design. Not all the level of granularity control theories can be used in the design of the actual working chamber.
Forth, the sand making machine need the control for the grain type in the high-performance sand making production line. The experts of Henan Hongxing Mining Machinery use the computer control system to appropriately control the grain type of the materials.

Design of Hydraulic System of Hydraulic Cone Crusher

In order to effectively isolate and screen the useful minerals and ores, the material crushing has become the indispensable process in many industries. Recently, Henan Hongxing Mining Machinery has introduced the foreign advanced technology and developed the hydraulic cone crusher. Compared with the traditional crushers, the hydraulic cone crusher produced by Henan Hongxing Mining Machinery has significant features, which uses the advanced hydraulic technology and can better operate the crushing machine. In the future, it is expected that the hydraulic cone crusher will gradually replace the original spring cone crusher.
In this article, the experts of Henan Hongxing Mining Machinery will introduce the working principles and the project design of the Hydraulic cone crusher. The hydraulic cone crusher controls the actions of three basic circuits. The first action happen s when the fixed cone hydraulic locks the hydraulic cylinder. The second action happens when the hydraulic motor is adjusted between the fixed cone and the movable cone. The third action happens when the hydraulic cylinder is installed between the lock ring and the adjustment ring during the over iron release and cleaning up. It can support the upper locking ting on the adjustment ring to ensure that the fixed cone is in the crushing position of the adjustment ring when the hydraulic cylinder adds pressure in the crushing process. When you adjust the gap between the movable cone and the fixed cone, you should release the pressure of the locking hydraulic cylinder. The motor installed on the adjustment ring starts to run. The wheel gear on the motor makes the driving ring and the adjustment cap engage with each other to rotate fixed cone, which can be adjusted automatically. The over iron and the rack of the host are connected with each other and they are fixed together with the adjustment ring so that the adjustment ring and the rack of the host are stable. If the overload appears, the crushing equipment returns to normal situation. In order to clean the crushing machine, you need to separate the adjustment ring from the rack of the host.

Functions of the Rotary Kiln Cooling Machine

In the actual production, the high-temperature materials produced by the rotary kiln must be cooled to certain degree by the cooling machine to be transported. After the materials are cooled by the cooling machine, the materials can be elevated to the warehouse storage by the bucket elevator. The cooling machine can also recovery large amount of heat carried by the high-temperature materials, which can preheat the combustion air into the kiln to 3000℃ to 5000℃ in order to strengthen the calcined and reduce the energy consumption.
The cooling machine can be divided into the single cylinder and multi-cylinder. The single-cylinder cooling machine is similar as the rotary kiln. The single-cylinder cooling machine has the simplified body, rolling ring, roller, supporting device, the ring gear transmission, nose and tail. There is feeding device and the material cover according to the need. The difference is that there is not liner in the simplified body. You can install the heat exchanger means and the material plate in order to facilitate the heat exchange of the passing airflow. The cylinder of the multi-cylinder cooling machine is the same as the single-cylinder cooling machine. Every barrel is fastened by the two supporting points and the barrel body of the kiln. For comprehensive consideration, the kiln end is easily to be worn by the materials. Therefore, it should be made of the high alumina bricks with good masonry strength. Impacted by the mechanical transmission and high temperature, the middle segment should be made of the magnesium aluminum brick or high alumina bricks. The head of the kiln should be made of the clay brick, which is cheap. The ideal kiln liner is generally composed with two layers of refractory. One layer uses the lightweight insulation material to laid on the inner wall of the tube, which can also be poured by the unshaped insulation material. For the other layer, the bricks and wear-resistant materials can be used as the liner to directly contact with the flame. This kind of double brick is economical and reasonable.

The Structure of Hongxing Mechanical Grading Machine

The mechanical weight classifier can be divided into the leverage scale classifier and the spring scale classifier. The leverage scale classifier is mainly composed of the moving scale with circle movement and the fixed scale fixed on the rack of the classifier. The materials are loaded on the plate. When the moving scale enters the stoichiometric point, the measurement hook of the moving scale enters the measurement slide from the control slide. When the upward force of the measurement hood is larger than the downward force of the measurement slide, the measurement slide is raised. When the scale reaches the falling area, the plate will incline and the materials are poured. If the weight of the materials is smaller than the setting weight of the measurement value, the moving scale will continuously move forward. After going through the separation needle, the moving scale enters the control slide to move to the next measurement point.
The spring scale classifier is to combine the rotating screen with the plansifter according to the order of the increase of the classifying diameter. The gap between the two belt conveyor gradually increases. This precision of this kind of device is relatively low. However, the structure is simple and it is easy to adjust the machine. The operating rate is high and it is suitable for the large-scale classifying operations. 
The mechanical grading machine has simple structure and less failure. It is easy to increase the productivity. However, the metal is pourable in the transportation process. Sometimes, it is difficult to sort the materials according to the diameter of the materials. Therefore, for the irregularly shaped materials, the errors are easily to be produced. The mechanical grading machine is suitable for the classification of the metals whose size requirements are imprecise. The mechanical grading machine produced by Henan Hongxing Mining Machinery has stable working performance and there is no vibration. This kind of classifier can overcome the large vibrating work and the short service life of the plansifter. It will be your best choice for the classification work.

Features of Impact Crusher Used in Stone Production Line

In recent years, with the rapid development of China's high-speed rail, roads, housing and other infrastructure constructions, the artificial mechanism aggregates production gets a wide range of application. The aggregate production line which is composed by the crusher, sand making machine and conveyor belt can be seen everywhere. The mainstream model of the dry artificial sand and wet sand production line of the artificial sand process are gradually mixing together along with the comprehensive consideration of the factors such as environment and skills. The domestic artificial aggregate production is confronted with the salutatory development opportunities.
When we choose the crushing machine, we should consider many factors. We should first examine the manufacturers. The check content includes the strength of manufacturers, reputation and size. In addition, we should also pay much attention to the tonnage and the crushing amount of the crushers. You had better look at the specific technical parameters. Second, we should understand the matters needing attention, product quality, technical level and the degree of maturity. Third, we should inspect the production site of the manufacturers. The users’ scene is the most convincing. At last, you should shop around, carefully inspect and carefully choose the products. The price of a crushing machine is high. You should have a deep understanding about the manufacturers which produce the crushing machines. 
After the optimized design of the deep cavity-type rotor, the passing rate of the materials can be raised about 30%. The circle protection board with local attrition can be reused by the adjustment of the turn. The utilization of the materials can be improved. The service life of the impact crusher can be increased by more than 48%. The hammerhead with combined type can reduce the using costs, because you only need to replace the hammerhead part of the crusher. In addition, there is an additional hammerhead which can effectively prevent the damage to the stand plate after the attrition of the main hammer.  The core wear-resistant material is made by the highly wear-resistant and high-temperature materials used in the U.S. industry.  

Technical Performance of the Dual Rotor Impact Crusher

In order to prevent the shutdown of the motor because of the increase of the moment of inertia of rotation of the rotor, the dual rotor impact crusher produced by Henan Hongxing Mining Machinery uses the fluid coupling. In order to give full play to the crushing action of the two rotors, the crusher uses the dividing cavity crushing principles. In this way, the two rotors are responsible for certain crushing action. In order to improve the crushing effect, the two rotors have a height difference of 265mm so that the second rotor is force the feed to obtain the possibility to increase the line speed of the second rotor to improve the crushing efficiency.
For the counter plate body of the first and second counter plate, one end is jointed on the two side walls of the rack. The other end is hanged on the upper wall and the back wall of the rack by the special screw and the adjustment spring member. The impact plate of the sub-crushing chamber is connected by the connecting rod and locking spring installed on the upper rack by the hanging square cross-section axis. They are hanged between the two rotors to divide the upper rack into two crushing chamber. In the lower part of the impact plate of the sub crushing chamber and the second impact plate, there are grid plates with the different size of the gap so that the materials which have reach the particle size requirements can be timely discharged. This way can prevent the reduction of the working efficiency. Twisting and locking the spring nut can adjust the compressive force of the locking spring of the impact plate of the sub crushing chamber. At this time, you can change the gap between the lower part of the impact plate of the sub crushing chamber and the plate hammer of the first rotor to control the particle size of the materials in the second crushing cavity. Positioning nut twist can achieve the same purpose, but you must twist the nut of the locking spring to adjust the pre-pressure of the spring.

Introduction to Kinematic Analysis about Impact Crusher

The centerline and the centerline of the moving cone of the impact crusher intersect at a fixed point and they form an angle. Due to the characteristics of the structure, the movement of the moving cone is bounded by the eccentric sleeve and it has to do cycle exercise. In the mechanics, the materials do the space rotation around the fixed point. From the production practice, we know that the moving cone does the clockwise or counterclockwise cranking motion around the center line of the machine with the eccentric hole. In addition, it also does the rotation in the turning direction around the instantaneous axis with the eccentric sleeve.
When the impact crusher crushes the materials, the movable cone does the clockwise or counterclockwise cranking motion around the center line of the machine with the eccentric hole of the eccentric sleeve. At the same time, it also rolls along the materials layer of the crushing cavity. Why the state of this movement will appear? The excerpts of Henan Hongxing Mining Machinery will analyze the reasons for you in the following paragraph.
For the kinematics analysis of the impact breaker, we can know that both load operation and the no-load operation are small. Therefore, in the calculation of kinetic analysis, the operation can be considered as 0. The crushing cone of the impact crusher and the center of mass of the eccentric sleeve are not on their rotation center line. As a result, the inertial force and the fixed point are inevitably produced in the operation. The fixed point and the inertial force may increase angle. Since the angle is limited by the structure of the eccentric sleeve, it will not be changed. Therefore, the machine will produce a kind of harmful vibration if the rack sleeve and the spherical bearing shell produces a kind of action force. The eccentric sleeve is prone to be deviated, which will affect the normal operation of the machine. In order to eliminate or reduce the harmful vibration caused by this inertia force and moment of inertia and ensure the normal operation of the machine, the key is to calculate out the size of the inertial force and moment of the inertia force of the eccentric sleeve of the crushing cone.

Working Principles of Performance of Jaw Crusher

The jaw crusher is very widely used in the mining industry. This article will explore the working principles of the jaw breaker. One roller is supported on the fixing bearing, while the other roller is supported on the movable bearing. The movable bearing is pushed to the position of the stopper by the spring force. The motor drives the relative rotation of the two rollers. The materials are fed between the two rollers through the feed box. Since the materials suffer from the frictional force between the rollers and the materials, the materials are sent to the crushing cavity between the two rollers. After the materials are crushed and extruded, they are discharged from the bottom.
The minimum gap between the two rollers is referred to as the width of the discharge port. The granularity of the crushed products is determined by the size of the discharge port. The movable bearing can move along the horizontal direction. When the non-broken materials enter the crushing chamber, the stress of the rollers will suddenly increase. The roller and the movable bearing force the spring to move right so that the gap between the materials increases to discharge the non-broken materials. In this way, the bearing and other parts of the crusher will not be damaged. Therefore, it is the safety device of the crusher. Under the spring force, the movable bearing pushes the position of the stopper to the left. When the width of the discharge opening needs to be adjusted, you can change the position of the stopper. Therefore, it is also the adjusting device of the machine. The single-roll crusher completes the crushing work between the roller and the splicing lining plate which is installed opposite the roller. The liner may be smooth, grooved or toothed, but the roller surface must be toothed. Since the liner is hinged, its angle position can be adjusted so that it can change the distance between the liner and the roller. The liner is supported by a spring. When the non-broken materials enter the crushing chamber, the liner will move back for concession to discharge the non-broken materials.
The single roll crusher is also known as jaw roll crusher. The single roll crusher is composed of a rotating roller and a tooth plate. It has a lot of advantages. It has more compact structure and more excellent performance compared with the other crushers.

The Constitution of Simple Pendulum Jaw Crusher

This article will talk about the PEJ 900 × 1200 Type simple pendulum jaw crusher which is produced by Henan Hongxing Mining Machinery. The rack for welding the steel plate is the basic skeleton for the installation of all the parts. The fixed jaw and the moving jaw are fixed on the jaw plate by the crushing plate and the bolts which are made of the manganese steel. In order to improve the crushing effect, there are longitudinal corrugations on the surface of the crushing plate and the corrugations are relatively uneven. In this way, the ores can be easily crushed and they are easily to be bent.
There are manganese steel lining plates installed on both sides of the wall of the crushing cavity wall. Since the wear of the crushing plate is small and even, the lower part of the lining plate is worn seriously. To this end, the crushing plate is often made vertically symmetrical. In this way, after the lower part of the crushing plate has been worn, we can convert it for repeated use. The crushing plate of the large crusher is composed of many pieces of blocks, and each of the blocks can be interchanged, which can extend the period of use of the crushing plate. In order to make the crushing plate and the jaw plate can fit closely, there should be a liner which is made of a kind of plastic material between the crushing plate and the jaw plate. The liner is made of the zinc alloy or the aluminium sheet that should be very plastic. If the fit is not close, it will cause great local overload, which will damage the crushing plate, snap the tightening bolts or even cause the fracture of the moving jaw. The moving jaw plate is hung on the mandrel, and the mandrel is supported on the sliding bearing on the side wall of the rack. The moving jaw plate does the reciprocating swing around the mandrel relative to the fixed jaw plate.
The swing of the moving jaw plate is achieved by the crank and double rocker mechanism. The crank and double rocker mechanism is composed by the eccentric shaft, connecting rod, the former thrust board (antecubital board), and back thrust plate (back brackets). The eccentric shaft is installed in the main bearing on the side wall of the rack. The connecting rod (the upper link head) is mounted on the eccentric portion of the eccentric shaft.
