Effect of Ball Diameter or Rod Diameter Variation The first relationship to be considered is the effect of the variation of the ball diameter or rod diameter upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling these curves being deduced from the data of Coghill and Devaney.

Such mills are common in South African operations mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90 of critical speed) and often use "grid" liners to form an autogenous liner surface.

May 22 2019 · 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 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.In the past when primary secondary and tertiary crushers fed material directly to large ball mills the energy efficiency of the concentrator was determined for the most part by the ball mill operation whereas now the energy efficiency of a plant often rests largely on the SAG mill operation.

The SAG mill trommel undersize is combined with the ball mills discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80 passing 150 µm.

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation a portion of the charge is lifted along the inside perimeter.
