Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Industrial Ball Mill Grinders | Pulva
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.
