    What it is the optimun speed for a ball mill

    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.

    Rod mills, how they function Mine Engineer.Com

    Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
