A ball mill is still the preferred solution for many types of dry grinding duty. A ball mill consists of a rotating horizontal cylinder, containing a cascading grinding media, typically steel or ceramic balls, in the range of 10 to 100 mm diameter. The grinding mechanism takes place within the falling and sliding grinding media. The feed ...

Ball 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 ...

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.
