An apparatus and methods for controlling the location and distribution of loose ceramic particles in a ceramic metal composite component formed via casting. A retaining structure that may include loose ceramic particles is placed in a casting mold at a desired location for ceramic particles in the composite component prior to pouring molten metal into the casting mold. Alternatively, the loose ceramic particles may be introduced into the mold concurrently with the molten metal.

Composite components formed with loose ceramic material

Chutes and other components may include composite liners to improve performance. Composite liners generally comprise a base metal having a ceramic material embedded therein. The composite liners exhibit improved resistance to wear and, therefore, have a longer usable life than liners formed of the base metal alone.

Composite chute liners

An elongated impeller shoe 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 an elongated supporting base member 28 for attaching to a turn-table bracket 20 in which the base member 20 is cast of a high strength steel alloy material. The base member 28 has a wide longitudinal female dovetail groove 54 formed in a front face 38 thereof extending between an inner end 32 and an outer end 34. The groove 54 has a shallow taper downward from the inner end 32 to the outer end 34. The assembly 10 includes a wear resistant member 30 mountable to the base member 28 for receiving the material from a central distribution disc 15 and directs the material radially outward along a front face 82. The wear resistant member 30 has a complementary male dovetail projection 100 formed on a back face for slidably fitting into the female dovetail groove 54 to releasably secure the wear resistant member 30 to the base member 28. The base member 28 and the wear resistant member 30 have respective shoulder and abutment surfaces 48 and 108 for engaging each other to maintain a loose fit between the dovetail elements.

Impeller shoe assembly

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.
