The ball mill can be operated in a wet or dry way, depending on the material properties and the intended use. The wet ball mill is usually preferred when the material to be ground is wet, such as in the case of ore processing. On the other hand, the dry ball mill is suitable for grinding dry materials, such as cement, limestone, and coal.
