Abstract

A roller mill includes a substantially horizontal grinding table, at least one roller operating interactively therewith which is configured for rotation about its centerline by means of a roller bearing and being connected to a roller shaft. The roller mill also includes a force device for at least partial absorption of an axial force originating at least from the roller and acting in the longitudinal direction of the roller shaft. The force device comprises a first part mounted on a machine component which is stationary relative to the longitudinal direction of the roller shaft and a second part mounted on a machine component rotating about the centerline of the roller and co-rotating therewith. The first and second parts comprise opposing pressure surfaces which both extend substantially perpendicular to the longitudinal direction of the roller shaft and form between them a compartment. The pressure surface on the first part is oriented in the opposite direction to the axial force acting in the longitudinal direction of the roller shaft and the pressure surface on the second part is oriented in the same direction as the axial force acting in the longitudinal direction of the roller shaft. An apparatus configured to introduce a pressurized viscous medium into the compartment between the opposing pressure surfaces is also included.
