A fixed roller pulverizing mill wherein there is comparatively little wear, vibration or other adverse characteristics and wherein a uniform fineness of the ground material is maintained. The rollers, which do not move substantially in a horizontal direction, bear down on a rotating table, contacting the table at a circular trough therein and are individual spring biased to improve the performance of the mill.

An apparatus is provided for pulverizing material into comminuted particles in which at least three rollers are mounted for rotation and maintained in contact with the material on a grinding ring. The rollers are suspended in a manner to allow the rollers to swivel about respective vertical axes perpendicular to their respective axes of rotation.
