ABSTRACT:
A centrifugal impact rock crusher having a centrally located rotary impeller table with a feed cone centrally located on it is equipped with a vertically reciprocating feed chute located above the feed cone. The mouth of the feed chute periodically moves downward to partially surround the feed cone to vertically distribute radial flow of material being crushed and thereby reduce concentration of impeller shoe and anvil face wear during crushing of uniformly sized gravel.
