Abstract

The roller mill for grinding of material to be ground prescribed by the invention has a grinding table and at least one grinding roller which works with the grinding table, whereby a water lance for applying water to the material to be ground is placed in the rotation direction of the grinding table in front of the grinding roller. The water lance is designed to rotate and means for rotating the water lance are provided in order to specifically influence the exposure time of the water to the material to be ground before the material to be ground is gathered by the grinding roller.
