A ball mill consists of a hollow cylindrical chamber (Fig. 6.2) which rotates about a horizontal axis and the chamber is partially filled with small balls made of steel tungsten carbide zirconia agate alumina or silicon nitride having diameter generally 10 mm. The inner surface area of the chamber is lined with an abrasion-resistant material like manganese steel or rubber.

Chat OnlineIf 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. Ball mills may be primary or secondary grinders.
Chat OnlineBall milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion the particles in between the media and chamber walls are reduced in size by
