Typical AG/SAG feed particle sizes range up to 30 cm (12 inches) which corresponds with the product size of primary crushing. They do require primary crushing so that the randomly sized run-of-mine ore is reduced to a uniformly distributed feed size acceptable to the AG/SAG mill. AG/SAG circuits do not require secondary and tertiary crushing ...
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 ...
