Ball Mills in the Mineral Processing Industry

Loading the Mill: The ball mill is loaded with the material to be ground and the grinding media (balls). The material can be fed into the mill either wet or dry. Rotating the Mill: Once loaded, the cylindrical shell starts rotating around its horizontal axis. Various mechanisms, such as gears, belts, or direct drives, can facilitate this rotation.

Ball Mill (Ball Mills Explained)

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
