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.

An impeller shoe is described for mounting on the turntable of a centrifugal impact rock crushing machine for directing the aggregate radially outward from a central distribution cone to stationary anvils. The impeller shoe is elongated with a trapeziform shape. The impeller shoe has an inclined face working surface with an angle of between 10 and 12 degrees with respect to a back bearing surface. The shoe has inner and outer ends having inner and outer end surfaces respectively that extend transversely between the back bearing surface and the face surface. The inner and outer end surfaces are oriented at acute angles with respect to the back bearing surface. The inner end surface is oriented at an obtuse angle with respect to the face working surface. The outer end surface is preferably oriented at an acute angle with respect to the face working surface. A stepped notch is formed in the inner end complementary the contour of the central distribution cone to enable the inner end to engage and overlie the edge of the distribution cone to hold the cone in place.
