# ball mill torque and power rating calculations

V-Belt Drive Selection Handbook - Baldor NOTE: An original aspect of this guide pertains to the power rating calculation. The basic power rating is evaluated according to the size of the sheave & the speed of the drive. A length correction factor and an arc correction factor have to be applied to adjust this basic power rating depending on the ratio and the center distance.

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.
