| 摘要 |
The invention concerns a method of influencing the degree of grinding of material which is fed into the peripheral portion of the grinding chamber of a mill whose inclined and upwardly-divergent open bowl or plate-shaped grinding chamber has a central outlet for ground material, said mill having a heavily inclined rotary shaft and at least one cooperating roller in the grinding chamber. The degree of grinding, which corresponds to the retention time of the material in the grinding chamber, is controlled by adapting the rpm of the mill and the incline of the rotary shaft, so that material in the section of the grinding chamber most inclined toward the horizontal plane slides downward toward the central outlet in steps corresponding to the desired degree of grinding.
