A material-bed roller mill including two adjacently arranged rollers which are oriented in an axially parallel manner and which rotate in opposite directions and between which a roller gap is formed, a foundation, two roller mountings, in each of which a roller is rotatably mounted, each roller mounting being secured to the foundation in a pivotal manner; and a clamping device. The clamping device is arranged outside of the roller gap and connects the two roller mountings. Each roller mounting has two rockers which are designed as separate components and each of which is arranged at an end of a roller and can be deflected independently of the other.

A roller grinding mill is provided that includes a grinding plate, grinding rollers, and at least two drives acting upon the grinding plate, and to a method for operating such a roller grinding mill. At least one grinding roller and substantially simultaneously at least one matching drive can be disengaged during operation. Thus only small radial forces are created that effect the radial bearing of the grinding plate.
