Feed Size VS Ball Size GrindingClassification

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

where d b.max 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.

Optimum choice of the make-up ball sizes for maximum

Sep 01, 2013For the feed size of 90% passing 18.9 mm (Fig. 6a), the maximum capacity was obtained with 100% of a make-up ball size of 50.8 mm. As the feed size is reduced to 13.4 mm, a 62:38 mix of 50.8 mm and 25.4 mm balls was found to be the optimum mix.
