Abstract

The invention relates to a material bed roller mill for crushing brittle material to be ground in the gap between two driven rollers which are pressed against one another with a high grinding force with a filling shaft for the delivery of material provided above the rollers. The width of the stream of material delivered to the roller gap can be altered with the aid of vertical guide walls which are adjustable at right angles to the vertical central plane of the roller mill while maintaining their vertical position. The column of material which is aligned vertically above the rollers creates pressure which is introduced fully into the material bed crushing and if required the column of material can be moved in the cross direction with respect to the rollers.
