The Intelligent Mill Liner Bolt. Up until now, SAG mill operations have lacked the means to intelligently determine mill liner replacements, other than the "blind" option of shutting down production, clearing the feed chute and doing a full, physical inspection of the mill lining and its wear depth.

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

Semi-Autogenous Grinding (SAG) is a method of grinding rock into fine powder whereby the grinding media consist of larger chunks of rocks and steel balls. A SAG mill is generally used as a primary or first stage grinding solution. SAG mill is a tumbling mill with a large rotating drum, is filled with ore, water, and steel grinding balls.

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. Amstar SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
