ABSTRACT:
The invention relates to a rotor for a rebound crusher in which the beater blades (5), retained in marginal recesses (4) in rotor discs (3) are positively retained by an axial locking system (7, 8) disposed on the rear side of the beater blades (5). On the front side of the beater blades (5) protective caps (10) are disposed on the discs (3) to maintain the axial positive locking system (7, 8) and protect the discs (3). To secure the beater blades (5) against axial displacement, the beater blades (5) are secured by a positive locking system comprising a recess (22) and a nose (21) engaging therein with clearance. To keep the protective cap (10) free from loading by the beader blade (5), in the side of the protective cap (10) adjacent the beater blade (5) a window (24) is provided into which a projection (15) of the disc (3) extends which forms an abutment (16 ) for a bearing surface (17) of the beater blade (5).
