SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, therefore, will become ...

First use of Sinamics SL150 cycloconverters for grinding mills: Siemens to modernize ore mill drive for copper producer Quadra FNX. Quadra FNX Mining Ltd., a Canadian mining company, has commissioned Siemens to modernize the drive in an SAG mill in its Robinson open-cast copper mine in Nevada, USA.
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. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
Siemens is responsible for engineering, manufacturing and supplying the electrical equipment of the ore mills. The SAG mill will be fitted with a gearless drive with an output of 24 MW. The ball mills will also be equipped with gearless drives, each of which will have an output of 16.4 MW.
