VIBRATING SCREEN FOR SORTING BULK MATERIALS

摘要

A vibrating screen for sorting bulk materials comprises a box with a screening surface and a drive with two self-synchronized vibrators located on the outer sides of the box boards and mounted on ends of a cross beam perpendicular to its axis. The axis of the cross beam passes through a center of mass of oscillating system, and its length corresponds to the width of screen and is connected to the box boards through inner and outer flanges having holes corresponding to fixing vibrator legs and made with an appropriate step, which is made with possibility of changing the angle of inclination of the longitudinal axis of relative to the vertical axis of the center of mass of the box.
