The Theory and Practice of Pharmaceutical Technology

Ball mills, cylindrical or conical drums rotating on a horizontal shaft are for fine grinding. Size reduction is done by grinding bodies moving freely inside the drum, exerting impact, compression, attrition and friction effects. The movement of the balls is determined by the degree of charging and the angular speed of the mill.

Ball Milling | Material Milling, Jet Milling | AVEKA

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 both impact and abrasion.
