Ball Mill Operating Speed - Mechanical Operations

2021-4-22  The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions are remaining the same, Speed of ball mill = [0.4886/(2p)] x

2008-3-31  The critical speed (rpm) is given by: nC = 42.29/√d, where d is the internal diameter in metres. 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, allowing the use of different sizes of grinding media.
