AMIT 135: Lesson 6 Grinding Circuit - Mining Mill Operator ...

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.

Mill Filling Prediction tool addresses productivity ...

SAG mills are a key asset for mineral processing operations as one of the critical stages of extracting mineral out of ore, and their continued stable operation is central to productivity. However, the performance of a SAG mill changes rapidly in response to conditions such as feed size and hardness as well as longer-term variability due to liner wear – something no instrumentation can directly observe.

When it Comes to Mining, Bigger is Best

HPGRs have been used successfully in mining operations over the years, indicating an increasing maturity of the product. As units become larger with higher throughput and deliver better reduction ratios than tertiary crushers, the combining of secondary crushers with HPGRs to replace SAG mills is oc- curring more often (Fig. 10).
