First, check the sealing degree between the vibrating screen frame and the screen body. There are sealing strips between the vibrating screen frame and the screen body for sealing. The sealing strips are made of three materials: silicone, rubber, and polyurethane. The vibrating screen will generate heat and friction during the screening process. After a period of use, the sealing strip will be deformed or broken. We recommend that users should regularly check the use of the sealing strip when using the vibrating screen, and replace it in time if it is damaged. The second is the reason for the damage of the screen. The screen of the vibrating screen is a wearing part, and different screening materials have different wear on the screen. When the screening machine is in continuous operation, the load on the screen is quite large, which will cause the screen to break. It should be discovered and replaced in time during the production process. To ensure the quality of the screened material. Finally, the running track of the material on the screen surface causes the small particle material and the large particle material to be unable to be completely classified. Usually, this situation is mostly a problem with the angle of the vibration motor. Generally, the motor angle of the vibrating screen is adjusted to 65 degrees when it leaves the factory. During use, the angle of the motor can be adjusted according to the screening situation of the material to change the running track of the material on the screen surface and improve the screening accuracy.
