Abstract
A breaker block, radial and rotational breaker block adjustment assembly and vertical adjustment means for rock crushers having an impeller mounted on a vertical axis. The breaker blocks are mounted in cell members forming a concentric circle about the vertical axis. The breaker blocks are detachably connected to adjustment assemblies which move the blocks toward the impeller as they wear and permit rotation if the impact face wears unevenly. An annular ring in one form of the invention supports the breaker blocks and cell members and is movable vertically in relation to the impeller.
