roll pass design calculation for structural mills

  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    To accelerate the math or calculation you can use the shortened formula Dm <= 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.
