ABSTRACT:
The invention relates to a method of operating a stirring ball mill which has a preferably cylindrical, rotating barrel provided with an inlet at one end and an outlet at the other end, in which a stirring shaft provided with stirring means rotates. This method includes operating the mill at supercritical rotatory speed with a degree of fill of at least 25%, while the balls are retained in the mill. In this manner a great throughput is achieved and a narrow grain size range, without requiring a great amount of space.
