ABSTRACT:
Rotary shredding apparatus for processing materials of various sorts in which the hydraulic drive for the counterrotating cutter shafts comprises a reversible hydraulic motor supplied with pressure fluid under the directional control of a fluid flow reversing valve. The flow reversing valve is controlled by a zero speed responsive device for sensing jam conditions that could stop cutter shaft rotation, thereby placing the valve in a control system which is independent of the pressure conditions in the fluid pressure system so that the hydraulic motor will continue to be supplied with pressure fluid up to the limit set by the usual pressure relief means.
