Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
In comparison to conventional tumbling mills, i.e., rod-and ball mills, the grinding media in an AG mill derive from the feed ore itself (Gupta and Yan, 2016;Hahne et al., 2003).
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.

AG Mill and SAG Mill. Feeding size: ≤25mm. Capacity: 0.65-615t/h. Output size: 0.074-0.89mm. Applications: It is commonly used in the mineral processing industry and ferrous and non-ferrous metal ore and nonmetal ore processing plants. It can also be used in cement plant, refractory plant, fertilizer plant and smelting plant.
The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred media detritor (SMD).
SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the …
mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On
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.

Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By …
semiautogenous grinding (SAG) mills and is the fourth paper in a series of five papers on Inferential Measurement of SAG Mill Parameters. The development of the inferential measurement models of SAG mill discharge and feed streams and mill rock and ball charge levels, detailed earlier in the series, is summarised.

It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don't possess a single hardness. The existence of this variance is what causes ...
