Abstract
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.
