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.

1.The transportation connecting bolts are not removed
2.The clamp bolts are not tightened
3.Vibrating screen collides with other equipment
4.Other fasteners are loose

1.The quality of the sealing ring: if the sealing ring is equipped with the original factory, it will be the silicone sealing ring provided by the regular supplier, but the accessories will need to be replaced after a long time. If the quality of the sealing ring purchased by the user is not good enough, it will break problem;
2.The diameter of the sealing ring of the rotary vibrating screen is not matched: the diameter of the sealing ring should be consistent with the diameter of the screen frame. So when purchasing related accessories, please choose the one you want to match to solve this problem.
3.Grinding problem of the upper and lower screen frames of the rotary vibrating screen: The location of the screen seal ring is between the upper and lower screen frames. For example, the contact part of the screen frame and the seal ring is not smoothly polished with burrs and other problems.

1.Improve the opening rate of the sieve plate. A high opening rate is beneficial to improve the screening effect; usually, the high opening rate of the stainless steel welded sieve plate can be paid attention to.
2.Adjust the feeding method, the feeding must be along the full screen width, and the screen surface must be fully utilized;
3.To reduce the porosity of the sieve batter, consider using a self-cleaning sieve plate, such as a spring rod type sieve surface or an anti-clogging device under the sieve.
4.If possible, consider adjusting the inclination angle of the sieve machine. A proper inclination angle is conducive to reducing the thickness of the material and realizing the screening of thin layers.
5.If conditions permit, wet sieving is an effective means to improve the sieving effect.
6. For the circular vibrating screen, the method of adjusting the counterweight can be considered to improve the screening effect;
7. For dry sieving, the incoming material moisture must be strictly controlled. When the moisture is high, ingredient sieving can be considered.
8. If possible, add a fixed screen at the feed end for coarse screening.
