ABSTRACT:
A roller mill, in which the milling rollers are pressed together with high pressures, has a fluidic device for imparting the respective pressure. This fluidic device comprises piston-cylinder units and a pressure line for the fluid. In order to obtain a skewing of at least one roller in dependency upon the pressure exerted by the fluidic device, pressure sensitive means are interposed between the pressure line and a displacing device for the skewing angle. In this way, a pressure signal may be transferred to a converter for converting the pressure into a corresponding displacement stroke. Preferably, at least one roller has a basic camber or crown which corresponds to a pressure within a lower range of the occurring pressures.
