ABSTRACT:
A shredder comprising a rotor and stationary structure. The rotor includes a shaft provided with a series of grooves and split blades mounted within said grooves, this by attachment means penetrating the shaft. The fixed structure forms an anvil or reaction structure having a series of independently removable, supported, upright transverse support blocks having hardened metal segments provided with upper cutting or shearing edges. The anvil structure includes an elongate cutter bar forming, with the cutting edges of said segments, a U-shape groove through which the individual blades pass. All of the hardened-metal, and preferably tempered steel cutting segments are completely supported by the fixed support structure and are usually independently and individually replaceable as may be needed through the operation of the machine. Ramp-providing rib structures are provided and are likewise split construction for easy removal from the interior hopper area of the shredder.
