Abstract

A centrifugal rock crusher that is convertible from a type utilizing anvils to a type utilizing a rock bed to define the impact surface includes a housing having upper and lower cylindrical portions, the upper portion being of a greater diameter than the lower portion, and a circular horizontal shelf ring connecting the upper and lower portions. An impeller disposed for rotation concentrically within the housing receives rock to be crushed and throws the rock outwardly into the upper housing portion. Anvils may be positioned along the shelf ring to define the impact surface and receive the thrown rock. Alternatively, the anvils may be removed and an insert may be provided that includes a circular horizontal shelf extension ring having an outer diameter equal to the diameter of the lower housing portion. The shelf extension ring is securable within the housing so that the shelf ring and shelf extension ring cooperate to define a supporting surface for a rock bed to define the impact surface for receiving thrown rock.
