Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.

The centrifugal classifier was also tested in the stand alone mode using an open circuit air swept ball mill to prepare the classifier feed. Data from these were analyzed to give size selectivity information for each classifier and to determine the effect of classifier design on the specific energy requirements of the air swept ball mill circuit.

The most common types of grinding equipment are ball mills. A BALL MILL grinds material by rotating a cylinder with steel grinding balls, creating the ball fall back into the cylinder and onto the material to be ground. Its rotation is depending upon the diameter of the ball mill and usually 4 to 20 revolutions per minute.
