ABSTRACT:
There is disclosed a rock crushing apparatus having a frame, an anvil mounted therein and a mounting for a rotor. The rotor has hammer elements disposed thereon for cooperation with the anvil. The rotor includes an outside surface, a plurality of recesses in spaced relation about the outside surface and a plurality of rotor protection members for protecting the rotor. The rotor protection members are releasably mounted in the recesses and extend outwardly of the outside surface of the rotor means for preventing wear of the outside surface. The hammer elements are releasably mounted in the recesses and in alternation with the rotor protection elements and extend outwardly of the rotor protection members. The hammer elements lift and pulverize the rock material. This arrangement has been found to be more effective than any of the prior art arrangements due to the configuration of the hammer elements and their disposition on the rotor.
