8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.

The batch ball and rod mills require a drive roll to rotate the mill the proper grinding speed, usually 60 - 75 of the critical speed for ball mills and 50 to 90 of critical speed for rod mills. The batch ball mill should be run between 56 RPM’s and 70 RPM’s. The batch rod mill should be run between 47 RPM’s and 79 RPM’s.

Formula For Critical Speed Of A Ball Mill

At low speeds the ball rolled over each other and attrition takes place. 1,2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that break contact with the wall and fall to the bottom to be picked up. In this manner impact stress will also be induced and the.
