Abstract:
A compactor comprising a compression chamber, ram means for compressing a slug of material, expulsion means for expelling the slug from the chamber and control means for maintaining continuous sequential operation.
Abstract:
A waste compactor comprising a longitudinally extending compaction chamber, having a discharge opening at its leading end and a feed opening at its trailing end. A chute communicating with the feed opening is provided by which delivery of refuse may be made to the chamber. A horizontally moveable ram is mounted to the rear of the trailing end of the chamber and is reciprocably moveable from a first position forward of the feed opening to a second retracted position to the rear of the feedopening, thereby to successively move the refuse toward the discharge opening. At least a portion of the compression chamber located between the feed and discharge openings is provided with a plurality of elongated flutes extending substantially along the path of movement of the refuse and radially extending through the inner surface of the chamber toward the center thereof.
Abstract:
A system for controlling the hydraulic ram of a refuse compactor comprising actuating the forward movement of the ram to effect the compacting and limiting the actuation to a first predefined time. Simultaneously sensing the pressure in system as a result of the compaction and on sensing of a predetermined level limiting the continued actuation to a second time period less than the first.
