Abstract
A flared distributor cap of a rotated impeller assembly directs material to be crushed radially outwardly to scoop-like impeller shoes which fling the material outwardly against breaker bars. The impeller shoes hook over mounting blocks and a pin and a screw will retain a shoe in place should the hook break. An annular distributor table carrying the mounting blocks and shoes has an annular, undercut groove in which interchangeable arcuate segmental wear plates fit. An undercut peripheral edge of a distributor cap overlies beveled, inner peripheral edges of the wear plates to lock them in position. Upper wear plates are secured to an annular distributor table cover, and have undercut grooves into which the cover fits.
