IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

The critical speed of a ball mill is the speed at which the centrifugal force is equal to the gravitational force acting on the balls. At this critical speed, the balls are held against the inner wall of the mill and do not fall to the bottom where they would be more effective at grinding the material. The critical speed of a ball mill can ...
