Calculation of Circulating Load in a Classifier. A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction. The term “circulating load” is defined as the tonnage of sand that returns to the ball
Ball Mill Critical Speed. 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 ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles. Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the
