Patent ID: 8500052

Claim:
A roller mill comprising a substantially horizontal grinding table; at least one roller configured for rotation via a roller bearing; a roller shaft connected to the at least one roller; a force device for at least partial absorption of an axial force originating at least from the at least one roller and acting in the longitudinal direction of the roller shaft, the force device comprising a first part mounted on a machine component which is stationary relative to a longitudinal direction of the roller shaft and a second part mounted on a machine component rotating about the at least one roller and co-rotating therewith; and the first and second part comprising opposing pressure surfaces which both extend substantially perpendicular to the longitudinal direction of the roller shaft and forming between them a compartment where the pressure surface of the first part is oriented in a direction opposite to the axial force acting in the longitudinal direction of the roller shaft and the pressure surface of the second part oriented in the same direction as the axial force acting in the longitudinal direction of the roller shaft; and an apparatus that introduces a pressurized viscous medium into the compartment.
