1. A scrap fragmentizer for reducing light scrap metal structures into small pieces of scrap metal, comprising:

  • (a) an apparatus housing having a scrap-receiving opening for receiving the metal structures to be fragmentized, and a discharge opening for discharging fragmentized pieces of scrap metal;

    (b) a source of hydraulic power for supplying hydraulic power to said fragmentizer;

    (c) scrap feeding means for feeding metal structures in the scrap-receiving opening into the apparatus housing;

    (d) scrap fragmentizing means powered by said source of hydraulic power and positioned in said apparatus housing between said scrap feeding means and said discharge opening for fragmentizing the metal structures into small pieces of scrap metal as they are fed to the scrap fragmentizing means from the scrap feeding means, and discharging the fragmentized metal structures through the discharge opening, said scrap fragmentizing means comprising a rotor having a plurality of outwardly-extending triangular teeth positioned in staggered relation around the periphery of the rotor, each of said teeth being aligned with the direction of rotation of said rotor;

    (e) an anvil positioned between the scrap feeding means and the rotor, said anvil having a serrated edge defined by a plurality of laterally-extending triangular-shaped serrations positioned in corresponding alignment with respective ones of said triangular teeth and having a triangular shape corresponding to the triangular shape of said teeth;

    the plane of said teeth and the plane of said anvil intersecting to cause passage of said teeth past respective ones of said serrations in closely spaced-apart metal fragmentizing relation to each other; and

    (f) wherein said teeth are spaced on said rotor so that only one tooth is in cutting engagement with said anvil at any one time.
