Abstract
Abstract The disclosed machine or apparatus for crushing is of the general type having a plurality of sets or pairs of opposing crushing rollers arranged in series through which the materials for treatment are passed. One roller from each set of rollers is rotatably supported by a frame. The other roller from each set of rollers is rotatably supported by a member movable relative to the frame. The rollers supported by the movable member move with that member relative to the frame supported rollers to provide for relief from shock loading between the opposing rollers. Resilient means resist relative movement between the opposing rollers in the separating or shock relieving direction.
