Abstract
A compaction apparatus (2) has a screw conveyor (4) for conveying waste material through a passage (6) and compacting it therein. An exit nozzle (10) is arranged to communicate with the passage (6). The nozzle (10) has a transverse internal cross--sectional area which enlarges and reduces respectively in response to increasing and decreasing material pressure. The screw conveyor has an axial shank extension at its outlet which extends into a compaction chamber located downstream of the screw conveyor and co-axial therewith. In use, the shank extension is surrounded by an annulus of compacted material in the downstream compaction chamber, such that the compacted material provides a support bearing means for the outlet end of the conveyor. A method of compacting waste or other material comprises the steps of conveying material by a rotating screw conveyor and compacting the material in a compaction chamber located downstream of the screw conveyor. The method further comprises supporting the outlet end of the screw conveyor during compaction by means of an annulus of compacted material which surrounds an axial shank extension of the screw conveyor projecting into the compaction chamber.
