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.

Roller mill for comminuting brittle grinding stock

The roller grinding mill for comminuting brittle grinding stock includes at least one grinding roller which co-operates with a counter-face in such a manner that the grinding stock is comminuted between the grinding roller and the counter-face and a pressing system for applying a force to the grinding stock via the grinding roller. The pressing system includes: at least one hydropneumatic store and at least one dual-articulation actuating cylinder. The dual-articulation actuating cylinder is connected to the hydropneumatic store and has two pistons and a housing which acts as a coupling rod.

Grinding mill with dual articulation actuation cylinder

The invention relates to a roller press having two rollers rotatably supported in a frame. In order to mount or dismount the rollers, at least one head piece of the frame can be removed from its operating position by being displaced outwards in the transverse direction. Such an embodiment is distinguished by inexpensive manufacture of the roller press and a time-saving mounting and dismounting of the rollers.

Roller press with displaceable head elements

The invention relates to a material bed roller mill having two rollers () which are rotatably supported in a machine frame () and driven in opposite directions and whose roller gap, which is charged from above with the grinding material to be comminuted, is delimited at its ends during the operation of the roller mill by a grinding material guide plate () which can be removed from its operating position, wherein
