    • 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).
    • 本发明涉及一种用于回弹式破碎机的转子,其中保持在转子盘(3)中的边缘凹部(4)中的打浆刀叶片(5)由设置在后侧的轴向锁定系统(7,8) 的搅拌器叶片(5)。 在搅拌器叶片(5)的前侧上,保护盖(10)设置在盘(3)上以保持轴向正锁定系统(7,8)并保护盘(3)。 为了防止打浆器叶片(5)轴向移动,打浆机叶片(5)通过包括凹部(22)和其中具有间隙的鼻部(21)的正锁定系统固定。 为了保持保护盖(10)免于被珠粒刀片(5)装载,在与打浆器叶片(5)相邻的保护盖(10)侧面上设有一个窗口(24) 所述盘(3)延伸形成用于所述打浆刀(5)的支承表面(17)的支座(16)。
