The set of rollers are configured for interactive operation with the grinding table and comprising a number of rollers each rotating about a roller shaft which is connected to the vertical shaft via a hinged connection with a center of rotation which allows a free circular movement of the roller in upward and downward direction in a plane comprising the centerline of the roller shaft. The center of rotation of the hinged connection in a vertical plane is located under the centerline of the roller shaft. The grinding table is rotatable about the vertical shaft and the roller mill may include mechanisms or devices that are sized and configured to introduce gases into the mill housing and may also include mechanisms or devices configured to allow for continuously diverting ground material suspended in gases out of the mill housing.
