Autogenous (AG) and semiautogenous (SAG) mills have been used for over 20 years for the coarse grinding of diverse ores (including gold, copper and iron ores). They offer advantages with regard to capital costs and operating expense compared to the secondary and tertiary crushers used in conventional sizereduction systems.
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.

It is obviously well understood that autogenous AG and semiautogenous SAG mills operate quite differently from conventional rod mill or ball mills. Since these mills are of a grate discharge type, they operate with varying loads, with the power drawn by the mill being dependent upon the volumetric load within the mill and factors that influence the viscosity of the charge, as shown in Figure 1.
Optional equipment isolation is available so that service can be performed without shutting down the lubrication system. Systems can be designed to lubricate using oils, greases and paste lubricants in both petroleum and synthetic bases. Click here to view our Open Gear Spray Lubrication System .
In these systems, seal leaks leading to water ingression are intermittent and are therefore hard to detect. A large Australian gold mine was experiencing problems with detection of seal failures on their large SAG Mill at the mine. The seal failures resulted in large amounts of water and process ore being ingressed into the lubrication system.
