To accelerate the math or calculation you can use the shortened formula: D m <= Km * d^ Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only singlesized balls and not a mixture without consideration for ball wear.
