Semi-autogenous grinding (SAG) mill liner design and ...

2016-6-6  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. These

2021-3-15  Adoption of autogenous or semi-autogenous grinding (AG/SAG) would lead to a significant simplification alternative to such plants. Within the scope of AG/SAG grinding, several approaches can be used in size reduction. For instance, the mill may be operated in the absence of steel grinding media (AG) or with steel balls (SAG) (Gupta and Yan, 2016).

What is the difference between a SAG mill and ball mill?

Principle of SAG Mill operation. 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%.[6][7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP ...

Small-Scale Continuous SAG Testing Using the

simplicity sake, the term autogenous grinding refers to both FAG and SAG grinding. In the last 10 years, smaller-scale tests have been developed to further address the variability of ore types, most notably the MinnovEX SAG Power Index (SPI) test [2], and more recently, the SAG Mill Comminution (SMC) test [3], developed by Steve Morrell.
