ABSTRACT:
The present invention provides an impact crushing apparatus that includes a housing, a chamber defined within the housing, a lid for closing the chamber and having an opening for receiving material, and a rotor assembly for receiving material from the opening in the lid and throwing the material radially outward. A drive unit is operably coupled to the rotor assembly. The rotor assembly includes a body with a plurality of receptacles and a plurality of tubes removably slideable within the plurality of receptacles, the tubes including a hollow bore configured to transport material from an internal opening of the rotor assembly to an outer periphery of the chamber. The tubes float within the receptacles and are retained by centrifugal force.
