Abstract
Two grinding rolls are mounted at a roll carrier. Below the roll carrier a grinding bowl is rotatably mounted on an axial thrust bearing for rotation about a substantially vertical axis. Below the axial thrust bearing there is arranged a drive device for the grinding bowl. A speed reduction gear arrangement is disposed between the drive device and the grinding bowl and contains a substantially cylindrical housing. This housing supports the axial thrust bearing and itself is supported by a substantially ring-shaped flange at a stand or framework at which there is also supported the roll carrier. The flange is connected to the roll carrier by means of a plurality of, for instance, four tie rods. Thus, the forces exerted by the grinding rolls on the grinding bowl and which are transferred therefrom to the housing and the reaction forces associated therewith are transmitted over a relatively short path via the flange to the roll carrier without loading any members of the drive device which are arranged below the flange.
