SAG mills (semi-autogenous grinding mills) TON

Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

What's the Difference Between SAG Mill and Ball Mill

Nov 26, 2019 Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel. SAG mills grinding media includes some large and hard rocks, filled rate of 9% 20%. SAG mill grind ores through impact, attrition, abrasion forces.

is the SAG mill discharge water addition rate measured variable 3[m3/hr] and SG l is the process water specific gravity [t/m ]. Step 2: SAG Mill Rock Charge The SAG mill rock charge properties (SMRC) and size distribution (smrc) are estimated by the reverse-application of the SAG mill grate discharge function on the SAG mill discharge stream

Semi-autogenous grinding (SAG) mill liner design and

operation of SAG mills. SAG mills are currently the technology of choice in hard rock milling operations for reducing primary-crushed ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m (34 ft) and above, with the largest being 12.2 m (40 ft) in

Optimizing your SAG mill operation International Mining

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.
