When the vibrating screen is used in multiple layers, the upper screen frame and the lower screen frame will look very compact with each other after they are placed. In fact, there will be some gaps. The strong vibration of the vibrating screen in operation can make some powdery or fine granular materials fly out of these gaps. At this time, if the gap between the screen frames is filled with the rubber strip of the vibrating screen, even if the vibrating screen vibrates strongly, the materials will not continue to fly out. Product function The rubber strip of vibrating screen has another function, that is to extend the working time of screen frame. To put it bluntly, the operation of the vibrating screen depends on the mechanical vibration force. The collision between the screen frames under strong vibration is inevitable, and the rubber strip of the vibrating screen is used to buffer them, reduce the collision between the screen frames, and its service life will naturally become longer.
