The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application.

This paper is the second installment of an ongoing numerical study of ball mills. The first installment (Cleary, 1998a) described the basic modelling of a 5m ball mill. Predictions of charge profile, charge segregation, power draw, torque, liner wear and collisional force distributions were made for a range of mill conditions.

Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 2575 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.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

For instance, in ball mills cataracting and cascading of balls in the upper part of the charge and the slip in the layer close to the liner are supposed to play the major role in comminution. Fig. 3 shows the snap shot of the ball charge in the centrifugal mill operated at J =, h = 20 mm, D = 100 mm and f = 20 s' .

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...
