Optimization of the Design of SAG Mill Internals Using

of SAG mill performance through 1. Changes in liner/lifter design to maximize throughput while maintaining acceptable wear levels. 2. Changes in ball size to maximize particle breakage without producing exceptionally high impact forces. 3. Changes in grate and pan lifter designs to decrease internal mill recycle and increase throughput.

(PDF) SINGLE STAGE SAG/AG MILLING DESIGN SINGLE STAGE SAG

The SAG mill model in the JKSimMet software has not been shown to accurately reproduce the performance of a single stage mill for greenfield design. A review of most modern power models shows that the prediction of specific energy is influenced by the high energy breakage characteristics of the ore (DWi, t 10 , SPI etc.) and the low energy (BWi).

In fact this is generally still the case in the multi-stream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills.

What Can Go Wrong in Comminution Circuit Design?

• SAG Mill Design Test (Starkey, 2006). There are reasonable correlations between all the tests’ data that generally allow any or all of the data to be used to design a SAG mill based grinding circuit for ‘typical’ ores of a moderate competence range. Issues have arisen where the expected SAG mill specific energy is greater than 10 kWh/t.
