Commonly the Ball mill speed is calculated as 77% of the critical speed. Mill liner thickness = 40mm = 0.04m Mill speed = 77% of the critical speed Critical speed (Nc) is the speed at which the centrifugal force is equal to the gravitational force. Nc = 42.3 /D1/2 D is the effective diameter of mill = Mill diameter – Liner thickness = 4.6 – (0.04x2) = 4.52m Nc = 42.3 / 4.521/2 = 19.89 rpm

At 2/3 rd speed at which centrifugation just occurs is called the critical speed of the ball mill. At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill. By this means the maximum size reduction is obtained by impact of the particles between the balls and by attrition between the balls. Generally it is 0.5 cycles per
