The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. Most ball mills operate at approximately 75% critical speed, as this is determined to be the optimum speed ...

The critical speed of ball mill is given by n c = 1 2 π g R − r. where R = radius of ball mill r = radius of ball. For R = 1000 mm and r = 50 mm n c = rpm. But the mill is operated at a speed of 15 rpm. Therefore the mill is operated at 100 x 15/ = of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls

N c = Critical Speed. Let's solve an example; Find the speed percentage when the mill speed is 24 and the critical speed is 6. This implies that; MS = Mill Speed = 24 N c = Critical Speed = 6. N% = MS / N c N% = 24 / 6 N% = 3. Therefore. the speed percentage is 3 m/s. Calculating the Critical Speed when the Mill Speed and the Speed Percentage ...
