The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the ball mill machine. The larger the diameter is, the slower the rotation is. If the peripheral speed of the ball grinding mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. Ball mill is the key equipment for re-crushing the materials after they are primarily

The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included. For such a small mill, one could also include the ore or powder charge.

Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a peripheral speed of 2.4 m/s. A mill of this size equipped with steel grinding media converts approx. 50 kW per m of feedstock.

For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200). High speed dispersers with no media run even faster rpm (1200-1800).
