Causes of poor feeding of vibrating screen

In the process of using the vibrating screen, the vibrating screen suddenly appeared more obvious that the material conveying was not smooth, and the problem that the material was discharged in a certain direction was followed. In fact, this problem can be said to be a relatively good "old problem" compared to a linear vibrating screen. Polyurethane screen manufacturers summed up 8 reasons to help you solve this problem.
1. Vibration motor installation problem
In a nutshell, the transportation and screening of the material by the linear vibrating screen is pushed by the vibration source body-the motor, which gives the material a designed and fixed size excitation force in a fixed direction. Therefore, if there is a poor transport situation It can basically be judged that there is a problem with the installation angle of the vibration motor.
Under normal circumstances, the manufacturer will carry out precise installation, test machine, and adjustment before the equipment leaves the factory to avoid the deviation of the exciting force direction, so this problem is generally not the cause of the new machine.
2. Vibrating screen has a large workload and a long working life
Compared with the relatively large linear vibrating screen, due to its heavy weight, if repeated years and repeated vibration and strong inertia, some parts of the body will appear loose, which will lead to changes in the angle of the vibration motor, so there have been various Kind of problem. What is to be done at this time is the problem of regular equipment maintenance.
3. Failure to feed evenly according to instructions
If feeding more or less, it is easy to cause unstable sieving accuracy, and due to the more or less material, the force deviation of the material is large, and the problem of the material is biased to one side, so the feeding should be uniform and continuous.
4. Installation base plane, spring support position change
In addition to the main sieving source power provided by the vibration motor to the linear vibrating screen, the linear vibration screen damping springs, bouncing balls, and sealing rubber rings that exist due to shock absorption more or less also affect the vibrating screen force and the linear The vibrating screen body is stable and solid. If a certain component has problems such as aging, it will be caused by uneven screen surface and unstable screen machine. , The life expectancy is greatly reduced, so regular inspection and maintenance are particularly important.
5. The weight error of the screen body is large, and the position of the center of gravity is not accurate
Under normal circumstances, this problem does not exist in regular manufacturers, but now the market is chaotic. Some manufacturers sell inferior imitation vibrating screens at abnormal market prices. Although the appearance is the same, there is no technical content, so users Shop around and choose carefully when choosing.
6. The position of the exciter and whether the two sides of the swing eccentric block are balanced
This problem is the same as the reason explained in the previous point. Manufacturers with their own R&D and installation teams will carry out precise installation and test machines, and such technical problems will rarely occur.
7. The stiffness of the shock-absorbing spring is inconsistent and damaged
Damping springs are no less important than vibrating motors in vibrating screens. They play an important role in maintaining the stability of the equipment and extending the life. If the quality of the shock absorber spring does not meet market requirements, it will inevitably cause a series of production problems.
8, screen box deformation
The screen box refers to the screen above the vibrating motor and below the feed opening, which is composed of a screen frame and a fixed screen surface around it. When the vibrating screen is working normally, especially for large and high-frequency equipment, the screen frame needs both the gravity from the large batch of screening materials and the strong excitation force of the vibrating motor. If the strength is not enough, deformation and damage problems are likely to occur. In particular, large mine vibrating screens need to pay attention to this problem. The strength of the screen box requires not only high-quality consumables, but also a unique welding process and an additional stable design.
The feeding is not smooth, and the discharge is a problem that often occurs with linear vibrating screens. Remember to "apply to the doctor" when you encounter it. The right medicine is the key, otherwise it will not necessarily be solved by spending a lot of money!
The above is the reason why the vibrating screen introduced by Chai Shang Trading Company is not smooth, and the output is biased.
