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).

Because of this more energy is needed to power up a ball mill as opposed to a rod mill. Rod mills can be operated at lower peripheral speeds resulting in reduced energy costs. Though this difference in power can vary depending on the type of ore you are grinding the consensus is that a rod mill requires less speed to perform the same function ...
