The use of vibrating screens is very wide, and many companies have used vibrating screens. Companies that have used vibrating screens for a long period of time also spend a lot of money on the use of screens. They will worry about the loss of the screens, and they are indispensable wearing parts on the vibrating screens.
The following are the reasons and solutions for the easy damage of the vibrating screen.
The main reason for the rapid damage of the vibrating screen: 　　
　　 1. The quality of the screen is an important factor that causes the screen to break too quickly. If the material of the screen does not meet the screening requirements of the material, the screen will be damaged quickly.　　
2. The screen generally has an upper screen layer and a lower stress layer. The two layers are required to be closely attached. If the pre-tensioning process of the screen is poor, when the stress layer at the bottom of the screen is tightened, the screen If the stratification is not tightened, the vibration distance of the screen when the screen is working is too large, and the part in contact with the screen frame cannot be compressed, which is also one of the reasons for the rapid damage of the screen. In addition, the tension of the screen is not enough, which causes the screen to vibrate, which is usually broken or damaged along the edge of the screen or at the edge bead.
　 3. The feeding problem of materials. Because the vibrating screen is constantly feeding, if too much material is fed at a time, it will hinder the normal movement of the material on the screen, which will not only easily loosen the screen, but also greatly reduce the processing capacity of the material. Giving a large amount of materials at one time will cause the load of the motor that is in unbalanced operation to increase suddenly, which not only easily damages the screen, but also easily damages the vibrating motor. Therefore, the materials must be fed evenly when placing the materials. In the feeding method with strong impact force, the vibrating screen must be equipped with a buffer hopper. The direct impact of the material on the screen will consume the exciting force generated by the vibration source, which is more likely to cause the screen to be damaged.

Causes of left and right vibration of linear vibrating screen and corresponding measures:
1. The screen is not tensioned. Tighten the screen or replace it with a new one.
2. Check whether the vibrating screen is placed in a flat position. For example, if the vibrating screen is not stable, change to a level ground or workbench, and the bracket is fixed.
3. Whether the transportation support is disassembled. If the transportation support is not disassembled according to the instructions of the machine, not only the linear vibrating screen will vibrate as a whole but also damage the whole machine.
4. Whether the angle of the weight of the motor needs to be re-adjusted; whether the motor running direction is the same, the motor running direction of the linear vibrating screen should be opposite instead of the same.
The above points are common problems that will cause abnormal operation of the linear vibrating screen

Under normal circumstances, many vibration devices are connected with even or multiple vibration motors when they are installed. Except for the single motor used for the rotary vibrating screen. Mine screens and linear screens are normally equipped with two motors. If you find a lot of noise during production, you can check the following three parts first to see if there is a fault: 1) Whether the roughness of the contact surface between the vibration equipment and the vibration motor foot is consistent Installation requirements; 2) Whether the anchor bolts are tightened; 3) Whether the vibration acceleration of the main engine meets the use requirements; if there is no problem in the inspection, it is worth noting whether the adjustment of the eccentric block of the vibration motor is correct. Note that the adjustment of the eccentric blocks on both sides should be consistent, to avoid the vibration of the vibration motor from side to side, which is prone to cracking of the foot. When some customers adjust the eccentric block, the included angle (or chord length) of the eccentric block at both ends is inconsistent, which will also cause the noise of the vibration motor. Furthermore, pay attention to the rotation of the two vibration motors. If both vibration motors are running in the same direction, your material will move to one side. The use of rubber springs can effectively reduce the noise of the equipment and reduce the friction between the steel spring metal and the metal during the vibration process. If you have done all of the above, please pay attention to whether the ground of your equipment is flat. If these conditions are avoided and there is still noise, then the material used in your equipment must be too saved, because the vibration motor and the equipment are integrated during the vibration process, which can also be called a vibration, but if the steel plate is thin Under the circumstance, there will be 2 resonances or irregular vibrations.

Insufficient tension of the screen: When the linear screen is produced for a long time, the material will hit the screen during feeding, which will loosen the screen and cause the material to concentrate on the slack position of the screen. For this problem, the status of the screen can be monitored at all times during production. Once the screen is found to be loose or damaged, it should be shut down and replaced immediately;
Motor excitation force is asymmetry: The power source of the linear screen is provided by two horizontal vibration motors. When there is a problem with the motor, the material will not move. For this problem, check whether the motor phase angles are the same, whether the eccentricity of the eccentric blocks of the two motors are the same and whether the motor turns;
Damping spring problem: The four corners of the linear screen are supported by four damping springs. On the one hand, this device plays a supporting role, and on the other hand, it also plays a role in the tilt angle of the screen box. Once there is a problem with the spring, it will cause the material to run off or not to walk. For this problem, the spring can be checked regularly. Once the spring is found to be broken, please stop the machine for replacement and adjustment immediately.
The above is the problem and solution of the material staying on the screen surface during the production of the linear vibrating screen. Linear vibrating screen, as a screening equipment with simple structure and large output, can be widely used in food, medicine, chemical, metallurgy and other industries

1. Insufficient tension of the screen causes the screen to vibrate greatly, which usually breaks or damages along the edge of the screen or the frame.
2. The quality of the screen is unqualified. Generally, the screen has an upper sieve layer (sub-network) and a lower load-bearing layer (parent network). The two layers are required to be tightly attached. If the tensioning process of the screen is poor , When the force layer at the bottom is tightened, the sieve layer is not tightened, and the throwing force of the material is greatly reduced during work, which affects the efficiency of the small fraction.
3. If the material stays on the screen for too long or too much time, the tension of the screen will be damaged, and the bag will eventually appear.

In the daily screening process, static electricity is generated due to the friction between the material and the screen, and static electricity makes the material clumps difficult to penetrate the screen, and it can also cause harm to the human body. So how to deal with the static electricity generated during the screening process? After many years of experience in the production of vibrating screens by our company, we believe that the following points are desirable to effectively handle static electricity in the screening process:

First, connect the ground wire (that is, the wire) on the screen to lead the current.
Second, add antistatic agent to the material before sieving.
Third, the materials go through a series of measures such as drying before screening.
Fourth, the materials are dried, high temperature and other measures before sieving.
