Hongxing Impact Crusher Is Favored by Many Customers

The impact crusher is the mostly widely used in various fields, especially the mineral resource crushing and processing area and the construction area. As we all know, the impact crusher can crushing the materials through the mutual action of the impact plate, liner and the rotor. Therefore, in the crushing process, the rotor and impact is the key to determine if the materials can be effectively crushed. The crushing cavity tends to be larger and lower. The secondary impact plate should be left behind. In addition, the discharging mouth at the lower end should close to the center horizontal line of the rotor to increase the fine crushing effect. Impact crusher is an efficient crushing equipment of mining industry, an indispensable machine for each mining company. Due to its simple structure, easy operation, competitive price, impact crusher was favored by mining industry. There are many crushing equipment manufacturers all over the world, and their levels are notably different.
If the impact crusher is divided according to the impact plate of the crushing cavity, the first-stage corresponding impact plate is called the first crushing cavity. The secondary corresponding impact plate is called the secondary crushing cavity. The third-stage corresponding impact plate is called the third crushing cavity. As a result, the impact crusher with the three-stage impact plate can strengthen selective crushing by increasing the number of the crushing cavity to increase the crushing degree of the materials. Therefore, adding the crushing cavity and using low rotating speed of the rotor can reach excellent crushing effect, which can also reduce the attrition of the plate hammer.
The crushing ratio of the impact crusher mainly depends on the length of the impact routine. If the impact routine with three-stage impact plate increases, the crushing ratio will be great. We can get the products with finer particle size. However, the structure is very complex. The design of the impact plate of the impact crusher is the design of the crushing cavity, because the impact plate is the most important component to compose the crushing cavity of the impact crusher.

The working device of the crusher machine is the main component which can be used to bear the work load. The strength of the structure can directly affect the stability and the working performance of the crusher machine. The experts of Henan Hongxing Mining Machinery have used the finite element method to do a lot of researches on the working device of the fixed crusher machine and they have got the force situation for stress, strain, displacement, safety factor and the rivet at any point of the structure of the crusher machine.
The working device of the fixed crusher machine is mainly composed of the rotary motor, the rotating mechanism, swing arm, bucket arm, connecting rod, rocking bar, hydraulic hammer, boom cylinder, bucket arm cylinder, turn hammer oil cylinder and other components. With different working conditions, the working device can bear different working load and the result for the finite element analysis is also different. The experts of Henan Hongxing Mining Machinery have got the position for the maximum stress point and the point of the maximum displacement with the research results. Therefore, the research results have provided certain basis for the further optimization, improvement and the design for the structure of the crusher machine.
According to the finite element analysis of the working device, we can know that the largest stress is less than the allowed stress of the crusher materials, which can meet the strength conditions. When the hydraulic system has the frequency of the excitation frequency and the external forces hydraulic system is close to the working device frequency, the resonance of the system will be caused so that the vibration of the working device increases.
The analysis about the integrated finite element can help us to better improve and design the various components of the working device. At the weak parts of the working device, we can increase the strength and the stiffness by using the analysis effect so that the distribution of the stress and the strain become more reasonable.

How to prevent the rustiness of the crusher machine and how to deal with the rustiness has become a very important issue in the actual use of the crusher machine.
How to prevent the rustiness of the crusher machine? When the crusher is removed from the storage, you must check the paint. You can repair the crusher machine according to the needs. Before the installation of the crusher machine, you should remove the preservatives from all contact surfaces. If the flywheel has been disassembled from the eccentric shaft, the contact surface between the flywheel and the shaft should be ensured to be coated with the preservative. During the storage period or the seasonal shutdown period of the crusher machine, the crusher and the parts should be stored in a firm stand to prevent the contact with ground. You should make the crusher machine run once every month for five minutes at least to ensure the correct lubrication of the bearing. If the crusher machine can not be operated correctly in the storage period, you should rotate the flywheel of the crusher machine with your hand for 3 times to 4 times so ensure that the bearing is lubricated correctly. Add grease to the bearings if it is needed.
The rust removal methods are the followings. You can make use of the impact role of the high pressure water jet and the water pry role to get rid of the rust and coating on the crusher machine. This method has no pollution or dust, which will also not damage the steel plate. The rust removal efficiency can be greatly improved.

Solutions for Common Faults of the Dryer Machine

The mining dryer machine is a kind of large machinery. The faults of such equipment will have serious impact on the work efficiency. In addition, the maintenance is also very difficult and complex. In this article, the experts of Henan Hongxing Mining Machinery will detailed analyze the common faults and the solutions for the dryer machine.
First, the mining dryer machine is explosive. There may be two reasons. On one hand, the materials in the dryer may be clogged and the temperature of the dryer machine is too high, which will cause inner fire. When the materials are clogged, we should immediately shut down the machine and completely clean the dryer machine. In order to prevent the occurrence of this case, we must do the daily maintenance work very well. If the temperature of the dryer is too high, we should reduce the fuel supply to reduce the temperature of the equipment to reach the production requirements.
Second, the finished materials can not be normally discharged after they are dried. The reason is that the installation of the dryer machine does not comply to the specifications. Gas leakage may cause low wind pressure.
Third, the fire phenomenon of the materials may occur in the dryer machine. There are four reasons. First, the specifications of the dryer machine can not meet the requirements. The device is small, but the materials to be dried are too many. Second, the design principles of the drying equipment are not reasonable. The manufacturer should replace the drying equipment. Third, the raw materials can not be absorbed, which may cause fire in the dryer machine. We should carefully check if the installation of the drying equipment is right and if the machine leaks the air. Forth, the use of the drying machine is not right. We should learn the using right method according to the using instruction manual.
Forth, the finished materials after drying are not even. This is because the materials are solidified into groups. We should first spread out the materials before drying. At the same time, we should correctively use the drying machine.

Kinetic Analysis of Jaw Crusher under Load Condition

As everyone knows, the rack of the crusher machine needs to withstand the periodically dynamic pressure of the motion components when the crusher machine is in the no-load operation. The vibration force of the rack brought by the inertial force can be used to optimize the balance to reduce or eliminate the dynamic pressure of the motion components on the rack. What is the dynamic force is like when the crusher machine is in the load conditions? The experts of Henan Hongxing Mining have carried out the dynamic analysis about the motion mechanism of the crusher machine in this kind of working conditions. You can use the corresponding dynamic analysis program to obtain the stress state of the main components of the revolute four-bar mechanism of the crusher machine in the load conditions. In addition, the 3D modeling software has been used to establish a three-dimensional model of the motion mechanism of the crusher machine. We can get the following conclusions.
The first is the stress analysis about the crank. The crank not only suffers from the action force of the weight of the eccentric part of the eccentric shaft. In addition, the crank also suffers from the constraint reaction force of the kinematic pair and the hinge kinematic pair.
The second is the stress analysis of the connecting rod (moving jaw). In a crushing cycle, the crushing process occurs when the angel of the spindle is between 60 degrees to 240 degrees. The size of the crushing force and the acting point size change with the turning angel of the crank. The peak value of the crushing force is at the 2/5 height of the lower part of the crushing cavity.
The third is the stress analysis of the elbow board. In the motion process of the elbow board, the inertia force and moment of inertia will be produced. Since the value of the inertia force and the moment of the inertia are too small, they can be ignored. The elbow board can be regarded as a two-force member which also suffers from the hinge constraint forces of the kinematic pair.

Research on Semi Industrial Ore Beneficiation Test

The semi-industrial ore beneficiation experiment is carried out in the special semi-industrial test plant or the workshop. The test can be a wholly continuous process. In addition, the test can also be a continuous or semi-industrial standalone test for the local job. The purpose of the test is to verify that the process programs of the laboratory and obtain the technological economic indicators similar to the production, which can provide a reliable basis for the concentrator design or lay the foundation for further industrial test. The equipment used for the semi-industrial test is the small-scale industrial equipment. There are no clear provisions for the scale of the pilot plant.
For the ore with complex nature and the new process and new equipment without enough production experience, the semi-industrial ore beneficiation test is very necessary. For the mineral area with rich resource, semi-industrial ore beneficiation test can be carried out if necessary to further improve and perfect the process flow and provide stable design data for the design of the new ore dressing plant. When the semi-industrial beneficiation pilot plant is established, you should take into account the possibility of testing for other mining ore. Therefore, the test content and device configuration should have certain flexibility. The semi-industrial pilot plant is actually a small processing workshop. The specifications and models of the equipment selected should be close to the industrial production equipment. The semi-industrial test is produced due to the complex nature of the ore, few production practices or the using of new technology in the design, or large scale of the concentrator. The process and the process parameters provided by the laboratory are not stable enough. The test content for the semi-industrial test includes the followings.
The first is the test ore samples. The semi-industrial test ore samples must be the ore samples taken according to the sampling design. The samples should be basically same as the samples from the laboratory.
The second is the analysis and identification for the original ore. The comprehensive analysis and identification for the original ore is generally no longer required. However, the multi-element chemical analysis, phase analysis, particle size analysis and ore containing the determination of the physical properties of the clay content, density and bulk density are necessary.
The third is the process structure. The semi-industrial tests are carried out based on the ore beneficiation methods recommended by the laboratory tests.
