### Ball Mills

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral

### Ball Mill

Wide Application of Ball Mill Ball mill, as the key grinding equipment of the materials, is widely used for mineral grinding such as cement, lime, quartz, slag, silica, iron ore, copper ore, gold ore, bauxite, calcite, barite, gypsum and other minerals in mining, quarry, chemical, cement and other industries.. Ball mill is the necessary equipment in ore beneficiation plant.

### Rod mills, how they function

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. Rod

### Ball Mill VS Rod Mill

For details, the grinding theory of ball mill and rod are different in many ways. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power
