Abstract: The centrifugal impact crusher includes, among others, a cylindrical housing (10), a turntable (22) supported by a vertical bearing (24), a series of ejectors (27) fixed to the turntable (22), a series of anvils (34) fixed to an anvil ring (30) around the turntable (22) and lining (14) on the internal wall of the housing (10). In order to damp out the significant impacts on the anvils (34), the anvil ring (30) is supported by a series of flat polygonal blocks (38) standing up on edge and resting freely via one of the flat sides on the upper horizontal edge of the lining (14) of the tank (10).
