Abstract
The material compactor generally includes a feed apparatus and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having confronting compression plates and an adjustably taperable portion. The area of the inner cavity of the final compaction chamber can be adjusted to become measurably smaller (tapered) or larger at the opened discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the chamber significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus and out an open discharge port.
