One of the main functions of the backing plate of the vibrating screen is to support the screen and prevent the screen from deformation or damage during vibration. By firmly fixing the screen between the back liner and the screen frame, the stability and screening efficiency of the screen can be ensured.
The tight fit between the backing plate and the screen frame can effectively prevent the material from leaking from the rear during the screening process, ensuring the accurate classification and screening effect of the material.
In the process of screening, the material will have a certain impact on screen. The presence of the backing plate can slow down the direct effect of these impact forces on the screen, thereby extending the service life of the screen.
