In order to obtain maximum capacity and efficiency, the screening equipment must be fed properly. The material should be spared evenly over the full width of the screening surface and should approach the screening surface in a direction parallel to the longitudinal axis of the screen. It must be fed at as low a particle velocity as is possible.
