ROLLER MILL FOR COMMINUTING BRITTLE GRINDING STOCK

摘要

According to a first exemplary embodiment the roller mill according to the invention for comminuting brittle grinding stock essentially consists of: at least one grinding roller rotatable about an axis of rotation, which interacts with a counter-surface in such a manner that the grinding stock is comminuted between grinding roller and counter-surface, wherein at least one grinding roller is constructed as a loose roller; bearing blocks for bearing the grinding roller, wherein the bearing blocks are horizontally slidable and are guided in the machine frame rotatably about a vertical bearing axis intersecting the axis of rotation; a pressing device supported on the machine frame in order to apply an adjustable grinding pressure to the grinding roller via the bearing blocks; and wherein 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, wherein the compensation elements are arranged between the machine frame and the bearing blocks. The compensation elements are - in the plan view of the roll crushing mill - arranged tangentially to a circle around the vertical bearing axis or constructed in a circular arc around the vertical bearing axis.
