ANVIL ASSEMBLY FOR VERTICAL SHAFT CENTRIFUGAL IMPACT CRUSHING MACHINE

摘要

An anvil assembly (10) is described for a vertical shaft centrifugal impact crushing machine (11) for increasing the effective utilization of the assembly and for substantially reducing the cost to utilization ratio. The assembly (10) includes a wedge-shaped supporting base member (22) for attaching to a bracket (20) in which the base member (22) is cast of a high strength steel alloy material. The base member (22) has a wide longitudinal female dovetail groove (46) formed in an inclined front face (36) thereof extending between an upstream face (38) and a downstream face (40). The groove (54) has a shallow taper downward from the upstream face (38) to the downstream face (40). The assembly (10) includes a wedge-shaped wear resistant member (24) mountable to the base member (22) for receiving the particulate material from a central turntable. The wear resistant member (24) has a complementary wide male dovetail projection (82) formed on a back face (90) for slidably fitting into the female dovetail groove (46) to releasably secure the wear resistant member (24) to the base member (22). The base member (22) and the wear resistant member (24) have respective shoulder and abutment surfaces (67) and (88) for engaging each other to maintain a loose fit between the dovetail elements.
