Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Iron ore grinding is completed in the ball mill, so the Iron ore ball mill is the main place for ore materials. Just like other ball mills, the Iron ore ball mill is mainly composed by a feeding part, an exhaust end, a rotation, and transmission part(a reduction box, an electrical machine, an electronic control, and pinion drive gear) and other parts.

Each ball mill is turned by a single 3,000 horsepower electric motor. These mills contain literally hundreds of thousands of three-inch diameter steel balls that pulverize the ore until it is like fine sand or face powder. Only then are the copper minerals broken free of the rest of the rock to be separated by flotation.

Grinding The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
Mill Is mainly used In ore, gold oriented, paper, energy, cement and other operations grinding Moms hardness 7 and humidly below %, the use of hot air, ground humidly can reach 10% -12 % of non- flammable explosive materials, such as solo types : clay, china clay, Benton, magnetite .
Processing of the run-of-mine ore starts with the grinding of ore to 80 weight percent below 75 microns. Grinding is done using an autogenous grinding (AG) mill, which uses the ore itself as a grinding medium. A small ball mill is used for the secondary grinding of pebbles sized material and .
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
