The AutoCharge system is primarily suitable for SAG mill balls (100–150 mm). As each ball rolls through the counting chute, an electro-mechanical limit switch is activated, signalling the counter. ... Each ball feeder/counter system is designed to accept a narrow range of ball diameters and should not be used to charge balls of mixed sizes.
Learn about the design and operation of SAG mills, which are primary grinding units for various ore types and circuit configurations. Compare SAG mills with AG mills and other comminution machines in …
Two formulations of combined state and parameter estimation (CSPE) for SAG mills have been presented. They incorporated novel dynamic models of SAG mill …
Depending on the structure of the mill, the type of job that the mill is most suited to perform is determined. SAG mills have coarser feed sizes (sag mill feed) and process more material due to the bigger diameter and length to diameter ratios. Ball mills employ steel balls as the grinding media and are suitable for both wet and dry grinding.
Feed Size, F80: Primary crushed ore is mandatory to feed any SAG mill. Typical feed size range is 80% passing 130 to 160 mm. Softer ores will be a little finer but the finer size is not sustainable when the ore becomes hard. Pre-crushing to finer sizes enhances throughput as does crushing of pebbles from the SAG mill (usually minus 60 mm).
In another research for the Cadia Hill SAG mill circuit, throughput increased by increasing the SAG mill ball charge, reducing the number of lifter rows, reducing the rock charge, …

(crushed ball mill feed to F 80 1.7 mm) to of SAG energy (crushed to F 80 152 mm). This benchmark project was evaluated where a 10 mm F 80 was being used. In order to be conservative, Starkey estimated that pre-crushing to ...
SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
The mill weight is measured by load cells or a strain gauge, and the controller adjusts the feed rate accordingly. SAG mills can be operated in open or closed circuit, depending on the downstream process requirements. ... The grinding media in a SAG mill are larger than in a ball mill, and there are fewer of them per ton of ore. The larger ...
