ABSTRACT:
A material reducing machine has a housing and a reversible rotor which revolves in the housing. On each side of the rotor the housing carries wear plates which pivot such that their lower ends will move inwardly, thus enabling the wear plate to serve as a deflecting vane for diverging windage away from the feed opening of the housing. Only the vane on the ascending side of the rotor is opened, the other being closed to serve as a wear and breaking surface against which the material is hurled. The grate beneath the rotor is in two sections with the juncture between the sections being directly below the axis of the rotor. At this juncture, the sections are provided with intermeshing teeth to prevent a gap from forming in the grate. The grate sections are supported on cages which pivot at their upper ends and are moved upwardly and downwardly at their lower ends by cams to adjust the spacing between the grate and rotor.
