In June 1998, the world's largest grinding mill, the 40 ft (12.2 m) diameter 20 MW Cadia gearless SAG mill, was commissioned. This was a leap of over 40% above the largest operating SAG mill. A significant saving in capital cost gave the incentive necessary for a single mill line at Cadia, resulting in the selection of the 40 ft (12.2 m ...

The SAG mill is 9.7 m in diameter and 4.8 m long. It is equipped with two 4,500 KW COMBIFLEX drives and has a rated throughput of 930 t of ore per hour. The 7.9 m x 12.4 m ball mill is powered by a 17 MW ring motor and has a rated throughput of 980 tph.
Our elastomer laboratory experts are continually developing new compounds for improved mill liner performance and wear life. Vulco© compounds are produced for use across AG, SAG, ball, rod and scrubber mills. Options include impact resistant alloy inserts of cast and rolled metals for the most arduous grinding applications, or ceramic and rubber mill discharge designs to prevent grate ...
reliable drive system for SAG mills. Early SAG mills had a diameter of about 32', later increasing to 34, 36, 38 and 40'. At the same time the mill volume also increased. Typically a SAG mill has a much larger diameter compared to its length. Yet the SAG mill of Newmont's Yanacocha mine in Peru is a single

Safe and speedy replacement. Thinner mill liners result in a larger volume inside the mill. This means you can have a higher charge level. Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill.
to manufacture the mill's main components in the most cost-effective location. Robust quality assurance Our engineers perform progress inspections to verify compliance with all applicable specifications and standards. The results are recorded and form a part of the mill installation record, which is maintained for the life of the installation.
Valby, Denmark – KAZ Minerals in Kazakhstan has selected FL as their technology partner for a new, 75,000 tonnes per day copper concentrator line at Aktogay. FL's scope of supply includes the key machines, installation supervision, commissioning, start-up and ramp-up support. The total order value is more than USD 100 million.
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.
SAG mill control, insight, and reliability. The throughput and efficiency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
Rod mills, ball mills, autogenous mills, and semi-autogenous mills (SAG Mills) all have a number of lubricating and hydraulic systems, and they must work to keep mineral output high. The mill systems oil is subject to extreme levels of very fine particles, and many operators believe the plant should be shut down periodically to change the oil.
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e.,
