The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
