Bingham, H L

A trailer chassis supports an apparatus for separating a lighter specific gravity material such as coal from higher specific gravity waste material. An open ended, elongated cylindrical drum is mounted for rotation about its axis inclined slightly from the horizontal, the drum bearing helical strips along the inner wall to drive the waste towards the inlet end. Water borne coal and waste enters the upper end of the drum. One of a plurality of annular baffle plates at the rear of the drum maintain a water level permitting floating of the lighter weight coal off of the heavier waste, where it spills over the baffles. A wire screen covers openings within the drum wall to the rear, between longitudinally spaced baffle plates to permit dewatering and removal of fine waste from the coal which exits the open rear end after passing from chamber to chamber, partially defined by the annular baffle plates. An auger underlying the chassis drives the water and fine waste forwardly. Water and fine waste is removed from a frontal screen area of the rotating drum, upstream of the discharge point for a chute bearing the water and unwashed coal leading into the drum.
