Abstract
A tub grinder which includes a comb on the floor adjacent the opening. The comb is movable toward and away from the rotor to adjust the size of the opening and to regulate the rate at which bulk material is impacted by the rotor. The comb also assists in preventing wads or slugs of the material from getting to the rotor. The tub grinder can also include notched bars below the floor for holding strings and fibrous material so that the hammers can cut them into shorter lengths. An air deflector can also be included to direct air flow from the rotor back toward the rotor. An adjustable restricter can also be included adjacent the rotor.
