Abstract:
Compacting apparatus comprising a screw conveyor for axial rotation to convey material through a passage and compact it therein, and an exit nozzle communicating with the passage, the screw conveyor being supported for axial movement relative to the passage during use, whereby the screw conveyor is axially moveable in the event of a blockage, and there being fixed blade means located adjacent the screw conveyor, and cooperating blade means carried by the screw conveyor, the blade means causing material located between the said blade means to be subjected to a cutting action by continued rotation of the screw conveyor, and the cooperating blade means extending over a greater axial length of the screw conveyor than the fixed blade means, whereby the blade means remain in cooperation over a range of positions of the screw conveyor relative to the passage.
