ABSTRACT:
A wood chip rechipping method and apparatus are provided wherein a slotted, cylindrical drum rotates about a concentrically mounted rotatable anvil rotor having a plurality of arms, each of which has a blade at its outer extremity. The drum and anvil rotor arms rotate in the same direction, but at different speeds. The rotating apparatus induces centrifugal force on the wood chips to position them against the inner periphery of the drum where the blades on the relatively faster rotating anvil arms shear off a chip slice having a predetermined thickness. This shearing action continues until each chip has been rechipped into slices capable of passing through one of the drum knife slots and into the discharge outlet.
