Claim Text:
1. A system for crushing a material, comprising: a compaction chamber including a proximal inlet portion configured to receive the material and a distal outlet portion having a substantially tubular geometry configured to allow crushed material to exit; and a cantilevered screw assembly having a shaft with a proximal portion at which it is cantilevered and a distal portion such that the shaft extends between the proximal and distal portions of the compaction chamber, a section of the shaft increasing in diameter in a proximal-to-distal direction such that a maximum diameter of the shaft is reached within the substantially tubular geometry of the distal outlet portion and the system is configured to crush the material between the compaction chamber and the section of the shaft that is increasing in diameter, the shaft further including a flattened portion extending from the section of the shaft that is increasing in diameter and that substantially maintains the maximum diameter of the shaft such that the flattened portion facilitates the crushing of materials to a desired thickness.
