The ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter figure 8.11.the feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. for an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. the rod charge must be maintained in good working condition, and broken and worn rods must be removed.
The point where the mill becomes a centrifuge is called the critical speed, and ball mills usually operate at 65 to 75 of the critical speed. ball mills are generally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns.
