Abstract
Waste compaction apparatus has a screw conveyor which conveys material along a passage toward an exit nozzle which constricts the flow, to cause compaction. The screw conveyor is slidably mounted on a shaft, biased toward the nozzle. This allows the screw conveyor to move axially during compaction to help remove or avoid blockages within the apparatus.
Claims9
Compacting apparatus comprising a screw conveyer for conveying waste material through a passage and compacting it therein, and an exit nozzle communicating with the passage, the nozzle defining an internal transverse cross-sectional area which enlarges and reduces respectively in response to increasing and decreasing material pressure, and wherein the nozzle comprises at least one resilient member which causes the nozzle to be biased toward a position of minimum cross-sectional area.
