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’senter a ball mill. Indeed, if a SAG mill discharge screen or trommel has 12.7 mm square openings, the top size of material moving forward to the ball mill will be 12 mm and the P 80 of the SAG mill discharge will be in the order of 4 to 6 mm, based on a normal relationship of screen opening to product size. According to Bond’s ball millPRE-CRUSHING OF SAG FEED: FRIEND OR FOE

Inferential measurement of SAG mill parameters II: state
The SAG mill discharge screen oversize conveyor measurement has also been utilised in a formulation that estimates a “mill discharge factor” parameter (Schroder, 2000) which is assumed to be or related to the maximum mill discharge rate coefficient, d 0 (h −1). Results and discussion.Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. TheseSemi-autogenous grinding (SAG) mill liner design and

Inferential measurement of SAG mill parameters III
Inferential measurements of SAG mill discharge and feed streams and mill rock and ball charge levels, detailed earlier in the series, are utilised in a simulation environment. A multi-variable, model predictive (MPC) controller simulation is developed from plant data and utilised to investigate the potential of utilising the inferential modelsAt one stage it was thought that the reduction in SAG Mill discharge open area was a contributor . allow the screen oversize to report to the SAG mill thus suppl ying sufficient coarse roTHE CADIA HPGR-SAG CIRCUIT FROM DESIGN TO
