Choosing a SAG Mill to Achieve Design Performance Choosing a SAG Mill To Achieve Design Performance John Starkey1, Principal Consulting It is possible in some cases to modify a SAG circuit to force it to perform better, but this often takes time, much effort and costly modifications
The task therefore shifts from SAG mill design, to how many tonnes will the given SAG mill grind in one hour When the difference between design methods used by different consultants reaches a factor of 2, it is time to stop and review the techniques used

of grinding media led to adoption of SAG and FAG flow sheets in certain iron ore plants recent developments in the understanding of blast through mill size reduction call into question the actual economies of SAG/FAG mills for processing cement, diamonds, and iron ore (Broeckmann and Gardula,) In the last few years HPGR-based plants to process , of the energy requirements of HPGR and SAG .
In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill
Within the world's 20 largest operations, the vast majority of production comes from milling operations, and in turn, the majority of these ounces come from high aspect ratio semiautogenous grinding (SAG) mill circuits
