Optimization of continuous ball mills used for finish

The results obtained with the semi-industrial ball mill (see Fig. 4, Fig. 5) were analysed regarding the number of stress events (calculated according to Eq. ). For an unchanged ball grading and the same true density of the feed material the number of stress events can be substituted by the average retention time of the feed inside the mill.
