  • What s the Difference Between SAG Mill and Ball Mill

     · 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. The calculation shows that the crushing ratio can reach 3000 4000 while the ball mill s

     · The Amps in a mill are a derivative of the Kg/KWh which is the ultimate most important indicator for steel balls consumption. When one make the integration of Amps vs. time one obtains the kWh so those parameters are proportional but also the kWh gives an indication of the mill efficiency. The balls coating is an interesting concept too.
