<p>A granulator for waste material having rotating and bed knives (62, 24, 48) respectively mounted for repeated detachment, sharpening and reinstallation with unskilled labor. Accurate predetermined knife gap distances are maintained by the configuration of surfaces on each rotating knife, whereby a cylindrical surface (74) thereon forming the cutting edge is coincident with a cutting cylinder (76) having a fixed location in the frame. Thus the cutting radius is unaffected by sharpening. <IMAGE></p> |
