Abstract
A roller mill for comminuting brittle grinding stock comprises at least one grinding roller constructed as a loose roller and rotatable about an axis and interacting with a counter-surface such that grinding stock is comminuted between the grinding roller and counter-surface. Horizontally slidable bearing blocks bear the grinding roller and are guided in a frame rotatably about a vertical bearing axis. A pressing device applies an adjustable grinding pressure to the grinding roller via the bearing blocks. At least two resilient compensation elements are associated with each bearing block in order to compensate a skewed position and/or deflection of the grinding roller. The compensation elements are arranged between the frame and the bearing blocks, and, in the plan view of the roller mill, are arranged tangentially to a circle around the vertical bearing axis or constructed in a circular arc around the vertical bearing axis.
