Semi-autogenous grinding (SAG) mill liner design and

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. These actions apply crushing, attrition and abrasion comminu-tion processes to reduce primary-crushed ores down to ball-mill sized feed.

SAG mills have a higher installed power density for a given plant footprint relative to AC mills.

SAG Mill Process Control Grinding & Classification

The purpose of a grinding mill is to convert electrical energy into rock breakage. The best use of that asset is to try to maximize the power draw. Try to hold the mill speed high and vary the feed rate to hold the weight (or bearing pressure), but watch out for "cycling" or "surging" that indicates instability in

SAG Mill Ball Charge The SAG mill was simulated to require a 10-12% ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in
