Jun 19, 2015 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 BALL MILL Objective: To Determine The (a) Critical

Yes. The right speed is critical to the success of a ball mill. Too fast and the charge just spins around the outside of the jar. Too slow and the charge just slides. You want a cascade. The right speed is a function of the jar's internal diameter. According to Cardew, the right speed is 64 to 87% of critical speed, which can be found The Effect of the Grinding Charge Trajectory on the
