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.
