Modelling SAG milling power and specific energy ...

01-01-2015  Accordingly, this will generate the possibility of increasing the SAG mill throughput, without affecting the product particle size going to the secondary ball mills. For SAG mill design, this model could help by generating a correction factor over the power (kW) calculated in the usual way by multiplying the specific energy in kW h/t (determined from experimental testing) by the projected capacity in t/h.

What's the Difference Between SAG Mill and Ball Mill ...

SAG mill vs Ball mill Crushing ratio. The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.

Difference Between Sag Mill vs Ball Mill - mech4study

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
