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.
Claims3
A rotatable grate means for a centrifugal crusher apparatus, said grate means comprising a plurality of grate bars, each of said grate bars having on opposite sides thereof cam means formed thereon, said cam means having the configuration of one half of a circle, wherein means are provided on said grate bars for assemblying adjacently lying ones of said grate bars into a continuous cylindrical hollow body forming said grate means, wherein said cam means of said adjacently lying bars form a plurality of apertures, each of said apertures having a predetermined conicity, said conicity having a larger dimension lying in the direction of grit passage through said aperture, and wherein a side of said grate bars lying in the direction of grit passage through said apertures has formed thereon between adjacently lying apertures roof-shaped projections for crushing and for guiding the grit material toward the adjacently-lying apertures, each of said projections running along the substantial length of the bar, wherein said cam means are formed on one side of said bars in a predetermined geometrical relationship with the cam means on the otherside of said bars for allowing a predetermined distribution of the apertures in each row with respect to the apertures in the other row, when said bars are assembled into said grate means.
