Abstract
A retaining wedge assembly for securing an impeller bar to the rotor of a horizontal shaft impact crusher comprises a recess defined in the rotor and sized to receive the impeller bar. The recess includes a first seat shaped to engage a first portion of the impeller bar and a second seat. A retaining wedge includes a first portion adapted to engage a second portion of the impeller bar, and a second portion sized to engage the second seat. A countersunk slot on the second seat receives the retaining wedge, which in turn cooperates to secure the impeller bar in the recess. Guide flanges may be provided for limiting axial movement of the retaining wedge. Thus, the impeller bar may be supported in the recess prior to start-up of the horizontal shaft impact crusher.
