  • Patent number: 5722607
    Abstract: The invention concerns itself with a hammermill, specifically for the fragmentation of metal car bodies, equipped with a shaft to which radially pointing rotor arms are attached, to the ends of which movable hammers are attached in the direction of the shaft rotation. The hammers are individually attached to the rotor arms, are U-shaped and embrace the end and sides of the rotor arms, thereby protecting the rotor arm ends and sides without requiring additional protective caps. On one of the preferred embodiments the positioning of the hammers is configured eccentrically so that an adjustment of the travel circle radii of the hammers is possible allowing greatly extended periods of operation of the hammermill.
