The refuse may be fed to the travelway 2 via a device 80 provided with rotating knives 81 and fixed blades 81a and is pushed along the travelway by angle-section bars 3 fastened to an endless chain 4. Fine material passes through a first portion of a reciprocating grid 21 into a hopper 22a, coarser material passes through a second portion of the grid 21 into a hopper 22b and glass and non-ferrous metals pass through a reciprocating grid 51 into a hopper 52. Ferrous metals are removed by a rotating drum 11 provided with magnets 12 and are discharged onto a chute 13 by blowing air into the drum. Plastics material is removed by a heated rotating drum 31 which discharges the plastics adhered thereto into a chute 33 with a screw conveyer 34. Paper and cardboard are removed at a station 40 by air blown through a perforated portion of the travelway by a fan 41, the air blast being confined by flexible curtains 44. Rags are removed by blowing air through the grid 51, the rags becoming adhered to a barbed conveyor 61 provided with a comb 62 which discharges the rags into a screw conveyor 63. Any refuse which is not removed arrives at a station 70. The material removed at the station 40 may be passed through an oven (36) to a chute (38) underneath which there is a fan (38a) which raises the paper without disturbing any plastics material present, Fig. 5 (not shown). The material collected in the hopper 52 may be passed between pairs of rollers (55) and then sieved to separate crushed glass from compacted metal, Fig. 6 (not shown). The refuse may be moistened as it moves along the travelway.
