ABSTRACT:
The screening efficiency of a gyratory screening machine, of the type having a moving base, is significantly increased by mounting to the base a spring/mass system which is tuned so that operation of the machine drive produces amplified movement of the mass along at least one of two perpendicular axes on which the base moves. Movement of the mass reduces the net force on the base along the axis on which the mass oscillates. The reaction force of the machine drive on the base along the other of the two perpendicular axes may be offset by a rotary counterbalance operated by the drive. Movement of the base relative to the ground is thereby reduced, and movement of the screen deck relative to ground is increased. This both increases the effectiveness of the screening motion and decreases the total reaction force transmitted through the base.
