Abstract
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.
