INVENTION: Control System For Operating A Comminuting Machine INVENTOR: Werner Doppstadt ABSTRACT OF THE DISCLOSURE The comminuting machine contains two disintegration shafts which comminute infed material. The two disintegration shafts are connected to respective pressure fluid operated drive motors which, in turn, are connected to respective pressure fluid main pumps like axial piston pumps drivingly coupled to a prime mover. A control valve acts upon an adjusting actuator for controlling the amount and the feed direction of pressure fluid delivered by the pressure flud main pumps and permit independent control of the pressure fluid operated drive motors. Pressure sensing means are responsive to excess pressure in feed lines leading to the drive motors and cause transient reversals of the pressure fluid main pumps and drive motors for removing blockage of the disintegration shafts. After a preset number of reversals an alarm is triggered.
