A method is disclosed for operating a roller mill of the type having a rotating grinding path upon which one or more grinding rollers are disposed for rotatably grinding the material to be ground. In particular, a method is disclosed for maintaining a constant predetermined thickness of the grinding cushion between the grinding roller or rollers and the grinding path. More particularly, according to the invention the mean grinding pressure increases within fixed limits when the mean thickness of the grinding cushion is larger than predetermined, and decreases when the mean thickness of the grinding cushion is smaller than predetermined. The invention also pertains to an improved roller mill of the type described, for practicing the inventive method.
