Cement production typical ball mill diameters

Apr 27, 2021

Aug 02, 2013 The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target P90 . Based on his work, this formula can be derived for ball diameter sizing and selection: Dm = 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm
