Device Functions
It is mainly used for the stale waste treatment. And its main function is to sort out large construction waste and rocks, and reduce the burden of subsequent pre-treatment.
Device Features
As the speed of each point is cyclically changeable, consider the maximum speed  of horizontal and vertical. Along  the screen, the speed is decreasing progressively. In the vertical direction of the screen, the velocity component is largest at the feeding end, and decrease progressively, which can ensure the  materials has big takeoff speed, and enough energy to move forward, thus improve the screen efficiency.
