  • Ball Mill Critical Speed Mineral Processing Metallurgy

    19062015  A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell The imagery below helps explain what goes on inside a mill as speed varies Use our online formula The mill speed is typically defined as the percent of the Theoretical

  • Variables in Ball Mill Operation Paul O Abbe®

    In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables Mill Speed is one variable that can often be easily changed with a variable frequency
