In modern mineral processing, semiautogenous (SAG) mills are important grinding equipment. A SAG mill has the advantages of high operation rate, large output, and large crushing ratio, which makes SAG mills have the characteristics of short process time, low management cost, and suitability for largescale production compared to other mills.

Autogenous (AG) and SemiAutogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that ...

The harsh and hostile internal environment of semiautogenous (SAG) mills renders realtime monitoring of some critical variables practically unmeasured. Typically, feed size fractions are known to cause mill fluctuations and impede the consistent processing behaviour of ores. There is, therefore, the need for continuous monitoring of mill parameters for optimal operation.

The autogenous mill can directly add the raw ore or the uncrushed ore in the quarry to the autogenous mill. It can grind the material at one time, which accounts for more than 20% ~ 50% of the total product. The crushing ratio can reach 4000 ~ 5000, which is more thanten times higher than the efficiency of the ball mill and the rod mill.
