Abstract
Improved tub grinding apparatus is described for grinding bulk materials. A concave restricter is positioned adjacent to and extends along the length of a rotatable rotor. The spacing between the concave restricter and the rotor is adjustable for determining the particle size of the resulting ground material. An auger is positioned adjacent to and along the length of the rotor for receiving ground bulk material and conveying it away from the rotor. The auger is laterally spaced from the axis of the rotor. The apparatus has a lower profile than conventional tub grinders.
