Planetary Ball Mills are suited for fine grinding of a range of materials such as soft, brittle, medium hard, hard, tough and moist materials. Material comminution involves high-energy impact achieved via the movement of grinding balls and rotating bowls. Grinding can be performed in various conditions whether dry, in inert gas or suspension.
