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.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [19.] A comminuter for reducing solid material to particulate form comprising:a frame;a tub including a cylindrical sidewall and a bottom disposed across an end of said sidewall, said sidewall being rotatably mounted on said frame;a first drive means mounted on said frame and drivingly connected to said sidewall for rotating said sidewall in a first direction;a disk rotatably mounted within said tub adjacent said bottom of said tub;a drive motor mounted on said frame and drivingly coupled to said disk to rotate said disk in a second direction; anda plurality of teeth mounted on said disk and protecting from said disk into said tub, the orientation of each tooth being individually adjustable independent of the orientation of each other tooth. .Iaddend..Iadd.
