ABSTRACT:
A tub grinder for grinding animal feed and the like of the type having a hammer mill extending below a stationary floor about which a tub side wall rotates, incorporates a rear discharge opening formed in a rear side wall of the hammer mill and includes deflector plates extending across an end wall of the grinder for directing material out the discharge opening to the rear of the tub grinder. Shear plates are adjustably secured to an end wall of the hammer mill housing. The shear plates are oriented in overlapping and angled relationship with respect to one another and to prevent ground materials from accumulating on the shear plates particularly when wet. Sickle blades are retractably positioned in the mill side walls for providing additional cutting action. Further, hammer assemblies are modified to include a knife edge and a face plate.
