Application of Dry Ball Milling in Mineral Processing
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.

Agitated media mills
Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.
