What Is Dry Ball Milling? Dry ball milling refers to a method of grinding or milling materials in a ball mill without the presence of any liquid or solvent. In this process, the material to be ground is fed into the mill in dry condition, and the grinding action occurs through mechanical forces exerted by the movement of the balls within the mill.

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.
