Abstract:
1. An apparatus for sorting material, the apparatus comprising: a frame; at least one first shaft rotatably mounted on the frame; at least one second shaft rotatably mounted on the frame in a substantially adjacent and parallel relationship with respect to said at least one first shaft, said first and second shafts defining a conveying surface along which material to be sorted is intended to travel via a rotation of the shafts; at least one single disc mounted in a substantially traverse relationship with respect to the at least one first shaft; and at least one compound disc mounted in a substantially traverse relationship with respect to the at least one second shaft, each compound disc having a main disc and an associated secondary disc, each main disc having an outside perimeter greater than that of the associated secondary disc, each secondary disc being in alignment with the at least one single disc of an adjacent first shaft, wherein the discs of the apparatus are arranged so that a spacing defined between neighboring discs on a first shaft is offset with respect to a spacing defined between corresponding neighboring discs on an adjacent second shaft.
