  • Publication number: 20230256471
    Abstract: The present invention relates to a screening apparatus (100) comprising a frame (10); a feed conveyor (20) mounted at one end of the frame and a screen (30) for accepting waste material from the feed conveyor, the waste material comprising fines and oversize material. The screen (30) is mounted on the frame (10) about a pivot axis and comprises a trough (32) with a top opening; and a plurality of driven elongate rotating members (40) disposed in an arc along one side of the trough and along at least a portion of the base of the trough (32) for causing circular or helical flow of the waste material within the trough. The trough (32) further comprises a base opening for discharging the fines material and an oversize material outlet for discharging the oversize material; and wherein the screen is mounted on the frame such that the elongate rotating members (40) are each independently perpendicular to the pivot axis.
