1999-11-1  The importance of stirred media mills in various industries and in research is steadily increasing. The comminution process in these mills is determined mainly by the number of stress events in the grinding chamber and by the intensity acting at these stress events: for a certain stress intensity a certain relation between the product fineness and the number of stress events exists.
