ABSTRACT:
Refuse is processed for land fill use by comminuting the refuse into smaller particles, blending the comminuted refuse to form an extrudable mass and continuously extruding the mass through a constricted die to form high-density, low-volume shapes which are suitable for burying in a land fill.
Apparatus for carrying out the process includes at least one reduction mill, a blender having a shaft carrying radially extending pitched paddles for kneading and blending the comminuted refuse into an extrudable mass and an extruder carrying a constricted die and having a screw feed for continuously extruding the blended refuse to form high-density, low-volume shapes. The bore of the constricted die defines an outwardly tapered land adjacent the discharge end for controllably accommodating the normal expansion of the compressed refuse shape prior to leaving the die.
