<p>A description is given of a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and similar materials. The roller mill comprises a force device (8) 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 (6). Said force device (8) comprising a first part (9) and a second part (10), where the first and second part (9, 10) comprise opposing pressure surfaces (9a, 10a) which both forming between them a compartment (11) where the pressure surface (9a) on the first part is provided so that it is oriented in the opposite direction to the axial force acting in the longitudinal direction of the roller shaft, and means (12) for introducing a pressurized viscous medium into the compartment between the opposing pressure surfaces. Hereby is obtained an efficient and adjustable force device for relieving the axial force exerted on the roller bearing which may thus be constituted by commercially available bearings.</p> |
