Comparison Statement With Ball With Rod Mill
21 CONCLUSIONS Continued In the present work, equations were also derived, giving zthe ball mill power drawP as a function of its dimensions internal mill diameter D and length L, zthe ball mill power drawP as a function of the feed D f (mm) and the product size d (mm), the Bond work index w i (kWh short ton) and the mill throughput T (short ton h), zthe ball mill dimensions (D and L), when.Dec 01, 2004 ) (5) D t D 0 = 1 D l D 0 exp ( K P t) + D l D 0, where, D l denotes the median size at the grinding limit. K P is the grinding rate for the sample under each condition. D t D 0 decreases rapidly in the initial stage of the grinding subsequently it tends to level off as the grinding progresses. The experimental data are fitted by Eq. .
