Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 25-75 microns. Both continuous and batch style ball mills use centrifugal force, gravity and hard media to break up industrial materials into fine pieces or powder. Ball milling systems grind dry material and wet slurry alike.
