ABSTRACT:
The comminution of solid materials, such as stumps and wood waste, into particulate form is accomplished by introducing the material to be comminuted into a tub. The tub is rotated to induce a circular motion to the material. Simultaneously, a disk positioned at the bottom of the tub is rotated, preferably in the opposite direction to the tub, in a plane parallel to the tub bottom. The disk has teeth thereon that impact the material in the tub. A screening means at the bottom of the tub is sized to keep the material in the tub until it reaches a desired particle size, at which time the particles can leave the tub through the screening means and enter a collection chamber. The particles are removed from the collection chamber by being entrained in an airstream that passes adjacent an opening in the collection chamber. Preferably, the teeth in the disk are individually replaceable and are symmetric so that once one side is worn the tooth can be reversed in its mount and used again.
