Abstract
Two racks of parallel screening bars each have rigid rack frames which extend beneath the bars. Two crankshafts with offset cam surfaces are mounted to the machine frame, and the rack frames are mounted by bearings to the crankshaft cam surfaces. The rack frame bearings are closely spaced beneath the bars to balance the system, while the rack frames provide a stiff oscillatory platform for the bars, permitting narrow gauge bars and increased screening area. The rack frames also include counterweights to dynamically balance the system.
