Abstract
Disclosed is a roller mill having two roller units disposed in a machine frame with each having one grinding roller rotatably mounted in two bearing jewels. The two grinding rollers are disposed mutually opposite each other and counter-rotatingly driven by a drive mechanism. A force-application system configured to generate a grinding force is coupled between the machine frame and at least one roller unit, wherein the grinding force is transmitted to the grinding rollers. The machine frame is composed of a plurality of frame parts, wherein for transmitting the grinding force a releasable and positive locking connection to two mutually compressed connection faces is provided between at least two interconnected frame parts, and/or between at least one frame part and one of the bearing jewels, wherein at least one of the two mutually compressed connection faces has a coating which generates a micro positive lock.
