### Calculate and Select Ball Mill Ball Size for Optimum Grinding

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^05 where D m = the diameter of the singlesized balls in mmd = the diameter of the largest chunks of ore in the millBall size depends on initial size of charge and ranges from 10mm150mm dia For particular material and initial size the ball size must be optimized Please referHow can one select ball size in ball milling and how muchThe ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter (Figure 811)The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weightBall Mill an overview | ScienceDirect Topics
