APPARATUS FOR MATERIALS COMPACTION

摘要

An apparatus (1) is provided for materials reduction. The apparatus (1) has a compaction chamber (32), a platen (36) for reciprocating between an extended position and a retracted position so that materials in the chamber (32) can be compacted, a securing arrangement for securing the compacted materials, and sensing means (63, 64) for sensing the platen positions in relation to one dimension of the compacted materials and pressure in relation to compactness of the compacted materials. The apparatus (1) includes a programmable controller programmed to initiate the securing operation when the pressure is at a predetermined pressure and the platen is at a predetermined position corresponding to a set dimension of the compacted materials. The securing arrangement is adapted to secure the compacted materials in a bale form and at the same time joining the securing materials for securing subsequent materials to be compacted. The compaction operation continues until the subsequent materials have been compacted to a set prepack dimension and are subject to a set pressure, at which an ejection operation is initiated for ejecting the baled materials through the gate (44). Materials to be introduced into the chamber (32) may be shredded beforehand by a shredder (24) or through a bypass inlet (26). A guide chute (30) can be arranged for guiding the materials into the chamber. The operations of the apparatus (10) can be diagnosed or controlled remotely by a computer.
