ABSTRACT:
A pair of cooperable rotatable discs of differing shape are supported in a housing for crushing hard and/or abrasive materials. A first one of the discs is planar in shape and is horizontally supported for rotation about a vertical axis. The cooperating disc is of conical shape, and is movable toward and away from the first disc along a second oblique axis, and is also supported for rotation in the housing about such oblique axis. Material to be crushed is deposited on the horizontal surface of the first disc, and after being crushed between the discs is carried by the first disc to be swept into the bottom of the crusher housing by means of a first rake or comb located above the upper material-bearing surface of the first disc. A second rake affixed to the lower surface of the first disc aids in discharging the crushed material from the bottom of the housing through an outlet chute.
