System for crushing with screw porition that increases in diameter

A system for crushing a material, comprising:

• a compaction chamber including an inlet chamber at a proximal portion configured to receive the material and an outlet chamber at a distal portion configured to allow crushed material to exit, said compaction chamber further comprising at least one wear member removably associated with the distal portion of the compaction chamber;
• and
• a screw assembly comprising a shaft that generally extends between the proximal and distal portions of the compaction chamber, a portion of the screw assembly increasing in diameter along a length of the shaft from the proximal portion to the distal portion of the compaction chamber such that the system is configured to crush the material between the compaction chamber and the portion of the screw assembly that increases in diameter;
• wherein the at least one wear member is configured to define a gap between the compaction chamber and the screw assembly through which the crushed material passes to the outlet chamber.

• and
• a screw assembly comprising a shaft that generally extends between the proximal and distal portions of the compaction chamber, the shaft comprising a portion that increases in diameter toward the distal portion of the compaction chamber, the shaft further comprising a flattened portion associated with the portion of the screw assembly that increases in diameter;
• wherein the at least one wear member extends around the flattened portion of the screw assembly;
• and
• wherein the system is configured to crush the material between the compaction chamber and the screw assembly.

• a screw assembly comprising a shaft that generally extends between the proximal and distal portions of the compaction chamber, the shaft comprising:
• a portion that increases in diameter toward the distal portion of the compaction chamber;
• a flight that extends about the portion that increases in diameter such that the height of the flight decreases toward the distal portion of the compaction chamber;
• and
• a flattened portion associated with the portion of the screw assembly that increases in diameter;
• wherein the at least one wear member extends around the flattened portion of the screw assembly;
• and
• wherein the system is configured to crush the material between the at least one wear member and the flattened portion of the screw assembly.
