ABSTRACT:
A centrifugal crusher having a rotor-crusher and a cylindrical grate rotatably mounted about it, wherein the grate is made up from a plurality of bars which on both sides having cam-shaped configuration such that when the bars are assembled, the adjacently lying bars form with their mating cams polygonal or circular apertures which serve as the calibrating apertures for the grit. The bars on their inwardly facing surfaces are formed at a roof-shaped angle to facilitate the material handling capacity of the grate.
