What it is the optimun speed for a ball mill ? - Pyrotechnics

Oct 19, 2006 · 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 be 98 RPM. Optimum RPM= .65 x Critical speed (cascading action of the media stops) Critical speed = 265.45/sqrt (Jar I.D. - Media O.D.) with dimensions in inches.
