ABSTRACT:
A machine for sorting refuse comprises a rotatable drum (1) having several succeeding processing stations (5, 6, 7) located between an inlet (3) and an outlet (4) and each including one or more rotatable shafts (8) the circumferential surfaces of which are equipped with goods-processing projections and which are mounted at openings in the wall of the drum, the processing projections being adapted to cooperate with the edge portions of the drum wall defining the openings, so as to bring about a processing action on goods fed from the inlet towards the outlet. The processing projections of the shafts (8) in a first station (5) most adjacent the inlet (3) are smaller than the corresponding processing projections in the following station (6) in order, in said first station, to separate fine goods, while allowing coarser goods, during the feed of the goods from the inlet towards the outlet along the bottom of the drum, to pass on for separation in a succeeding station or stations.
