Abstract
A roller mill () for grinding particulate material such as cement raw materials, cement clinker and similar materials has a substantially horizontal grinding table () and a set of rollers revolving about a vertical shaft (). The set of rollers includes a number of rollers () rotating about respective roller shafts () which are connected to the vertical shaft () via a hinged connection () which has a bearing shell () and a bearing journal () resting therein. The hinged connection () allows a free arcuate movement of the roller () in an upward and downward direction in a plane including the centerline () of the roller shaft. The set of rollers () is configured for interactive operation with the grinding table (), and the bearing shell () of the hinged connection () has a diameter which exceeds that of the bearing journal () resting therein by a factor of at least 1 percent.
