Difference Between Sag Mill vs Ball Mill - mech4study
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
Comminution - SlideShare
Tumbling mills for size reduction with either steel rods (rod mills) or balls (ball mills), or sized ore (AG & SAG mills) as the grinding media used depending upon the size and energy considerations. 2. Stirred mills represent the broad category of mills, which use a stirrer to provide motion to the steel, ceramic, or rock media.

considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the grinding plants that were built used FAG or SAG mills, and to decrease overall operating costs, many operators of older conventional milling plants considered and actually retrofitted their plants with AG/SAG mills.

2001). Increase in throughput has been realized by simply optimizing the feed size distribution to ... AG and SAG mills respond differently to changes in feed size. It arises from the fact that in AG mills some large rocks are required to break intermediate sized ones. If these large rocks are not
Energy Use of Fine Grinding in Mineral Processing ...
In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al.[19,20] found a scale-up factor for the Isamill of exactly 1, while Gao et al. imply that the scale-up factor for SMDs is 1.25.

The major reason of mill shut downs which lowers the mill availability is the time taken for replacement of broken or worn liners.
Mill (grinding) - Wikipedia
SAG mill. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also 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.
Digital Control Lab
Founded by Dr. Karl Gugel, Digital Control Lab started its life in 1998 as an electronics consulting firm known as DiCon Labs. During the early years, DiCon Lab was contacted by a leading cement manufacturer to replace microphone based systems for real-time mill loading measurements. The result was the first generation of MillScan products.
