ball mill rpm optimal
Oct 19 2006 Calculation of optimum speed depends on knowing the media diameter and jar also. For instance if your jar had in inside diameter of 90 mm and your milling media was mm diameter lead balls the optimum rotation would be 98 RPM. Optimum RPM=.65 x Critical speed (cascading action of the media stops)rpm optimal ball mill.
