What it is the optimun speed for a ball mill
Oct 18, 2006· Calculation of optimum speed depends on knowing the media diameter and jar I.D. also. For instance, if your jar had in inside diameter of 90 mm and your milling media was 12.7 mm diameter lead balls, the optimum rotation would be98 RPM. Optimum RPM= .65 x Critical speed (cascading action of the media stops)
