how can we calculate the rpm of ball mill

N c is the critical speed,in revolutions per minute, D is the mill effective inside diameter, in feet. Example: a mill measuring 110 diameter inside of new shell liners operates at 17.3 rpm. Critical speed is. C.S. = 76.63 / 11^0.5 = 23.1 rpm. Ball and SAG Mills are driven in practice at a speed corresponding to 60 81% of the critical

Rotation of ball mill at critical speed

If speed of rotation is low, it results in insignificant milling action as balls only move in lower part of the drum. If speed of rotation is very high, the balls cling to the drum walls due to centrifugal force. Therefore, intense grinding action is obtained only when drum rotates at critical speed and here the ball mill rotates at a speed which is neither slow nor very high.

Critical Speed Of The Ball Mill

The ball should be rotated with a speed that is equal to 70% of the critical speed, which is calculated from the formula given below. √ ( )-----(1) where, N c

The speed of the mill was kept at 63% of the critical speed. The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure. Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory. It was observed that the ball trajectories could be controlled by the face angle and the height of the lifter bars.
