SAG milling Process control abstract The operation of AG/SAG mills is sensitive to mill filling, therefore developing grindcurves to relate mill fillingto performance indicatorssuch as throughput,power draw, and product size can assist in achieving optimal mill operations. The throughput, power draw, and product size have been shown to peak ...
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. FullerTraylor SAG/AG Mills range in size from through in diameter with powers as high as 28,000 kW.
Every mining operation has a unique grinding process. has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAG/AG mills in the world. Our experts welcome the opportunity to assist you with circuit and circuit control design as well as startup, operation, and optimization of your mill.

mill, followed by a wide variety of rod and ball mills. Circuit configurations, including AG, SAG, ABC or SABC, are evaluated easily. The circuit employs an integrated Distributive Control System (DCS) for monitoring plant conditions. Feed rate, mill speed, power, mill load, particle size distribution and other data are updated,
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.

AG/SAG SE values to enable the additional power required for AG/SAG milling to be determined. AG/SAG inef ciency varies according to the transfer size fi (T80), whereby the ner sizes have less ineffi ciency than the fi coarser sizes. This means a closed circuit single stage AG/ SAG mill can operate at a reasonable ef ciency if the fi nal fi
