22626-215 ABSTRACT OF THE DISCLOSURE Combined hydrostatic/hydrodynamic bearing system for a grinding apparatus in which the material is ground in a grinding space defined between a pair of relatively rotating grinding mem- bers and in which at least one of the grinding members is carried by an axially displaceable rotatable shaft. One or more cylin- drical pistons are mounted on the rotatable shaft to rotate therewith within a pressure chamber defined within a stationary cylindrical housing permitting the piston or pistons to be displaced axially therein. Fluctuations in axial thrust forces acting on the displaceable rotatable shaft are counteracted by applying a fluid pressure medium to one or both of the piston ends of the cylindrical piston or pistons in a controlled manner so as to maintain a predetermined clearance range of the grind- ing space.
