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

Aug 02, 2013  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 mill feed in mm dk = the P90 or fineness of the finished product in microns (um)with this the finished product is

where d bmax is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m) Generally, a maximum allowed ball size is situated in the range from D /18 to D/24 The degree of filling the mill with balls also influences productivity of the mill and milling efficiency

• ## Feed Size VS Ball Size Grinding Classification

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill A f80 = 6 mm would need a ball size of 75 mm An empirical model from "Emerging Trends in Mineral Processing", 2005, is
