Formula For Calculating Ncritical In Ball Mill

18-07-2021· Find the diameter of balls when the critical speed of mill is 15 and the mill diameter is 10. This implies that; N c = Critical Speed of Mill = 15 D = Mill Diameter = 10 d = D – ( 42.3 / Nc) 2 d = 10 – ( 42.3 / 15) 2 d = 10 – 7.95 d = 2.05 Therefore, the diameter of balls is 2.05.
