ABSTRACT:
A combination tub comminuting apparatus and blower for simplifying and reducing the number of moving parts in a forage comminuting means. The comminuting portion comprises rotor means which rotates on a radius of the tub and is situated in an opening extending from near the edge of the tub to a point which is near the center of the tub. Since the forage is fed to the end of the cylinder described by the rotor rather than to the sides as in normal comminuting means, the length of the cylinder is very short compared to the diameter. The beating means grab the forage and pull it into the enclosure in pieces. Some embodiments of the concept include teeth on the stator enclosure for the rotor to provide further comminution before the rotor executes its final step of forcefully discharging the comminuted forage, via the beating means, in a blower-type action.
