No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product. Too fast and inefficient media movement (known as cataracting) will generate high impact but also greatly increase mill wear. Even faster

The critical speed n (rpm) when the balls remain attached to the wall with the aid of centrifugal force is: n = 42.3 D m. where D m is the mill diameter in meters. The optimum rotational speed is usually set at 65%–80% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of the ball size is

the rotating charge inside most industrial ball mills. Most industrial ball mills have lifters. Data from 40 ball mills show that the average critical speed is 0.73 (Morrell, 1996). Research in mill charge motion (eg. Mishra and Rajamani, 1992; Inoue and Okaya, 1994) reveals how the charge motion vary with mill speed and liner/lifter profile

Critical Speed_ When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill. This instantaneous speed of the mill is as follows: N0 —- mill working speed, r/min; K’b — speed ratio, %. There are many layers of grinding media in the mill barrel. It is
