Abstract
An improved impeller and replaceable impeller wear parts for a rock crusher having a turntable driven by a vertical drive shaft. The impeller assembly consists of wear pins, wear plates, and block members and heel plates which are mounted on a removable tray which may be lifted from the turntable as a unit without removing the heavy turntable from the drive shaft. Interchangeable wear pins and wear plates are quickly and easily relocated within the impeller assembly or replaced. The wear pins are characterized by double lugs in the top and bottom of projections in a generally cylindrical metal pin which interlock with cutouts in the wear plates.
