Ball Mill Parameter Selection & Calculation - Power
Aug 30, 2019· The wear of grinding steel balls is related to the surface area of steel balls. In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
To accelerate the math or calculation you can use the shortened formula: D m <= Km * d^0.5where 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 single-sized balls and not a mixture without consideration for ball wear.
