ABSTRACT:
A shredder, crusher, hammermill, ringmill or the like is provided with a multi-sided rotor shaft to which spider arms and hammers are mounted. The rotor shaft has at least one pair, and preferably two or more pairs, of opposing sides. The hammers are pivotally mounted between supports in the shape of spiders or discs. The supports include openings which have straight sides corresponding to the number of straight sides on the rotor shaft. The straight sides of the support openings engage the rotor shaft straight sides. Hence, the supports are rotationally fixed in place relative to the rotor shaft without the use of keys and keyways, pins, bolts, or other types of fasteners, allowing for easier assembly and reduced maintenance costs for the crusher.
