The point where themillbecomes a centrifuge is calledthe "Critical Speed", and ballmillsusually operate at 65% to 75% ofthe critical speed. BallMillsare generally used to grind material 1/4 inch and finer, down to the particlesizeof 20 to 75 microns.

The formula tocalculate critical speedis given below. N c = 42.305 /sqt(D-d) N c =critical speed of the mill. D =mill diameter specifiedin meters. d = diameter of the ball. In practiceBall Millsare driven at aspeedof 50-90 ofthe critical speedthe factor being influenced by economic consideration.

Thecritical speed(rpm) is given by: n C = 42.29/ √ d, where d is the internal diameter in metres. Ballmillsare normally operated at around 75% ofcritical speed, so amillwith diameter 5 metres will turn at around 14 rpm. Themillis usually divided into at least two chambers (although this depends upon feed inputsize-mills…
