What it is the optimun speed for a ball mill ...
19/10/2006 · 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)
