The design of the 40-foot diameter SAG mill installed at the Cadia Gold Mine, New South Wales Australia, followed after two years of extensive laboratory and pilot plant testwork. This showed the Cadia ores to be hard and competent necessitating the use of both a variable speed mill drive and pebble crushing. The grinding power requirements were based on engineering in-house …

The 40-foot (40') SAG mill now receives a feed of predominantly high pressure grinding rolls (HPGR) product with a minor component of secondary crushed ore at a combined F80 of 17mm. This significant reduction in feed size to the SAG mill has markedly changed the operating characteristics of the mill, which has been extensively studied since commissioning in 1998.

The Cadia SAG mill diameter is 40 ft and the ring motor that drives the mill is rated at 20 MW. In 1998 when the mill and motor were commissioned both were the largest machines of their type in the world. The stator exhibited vibration excursions that appeared to …

SAG mill characteristics. Diameter inside shell = 12.2 m (40 ft) EGL = 6.1 m (20 ft) Ball filling = 12% v/v; Total filling = 25% v/v; Mill speed = 78% of critical (Lane et al, 2013 appears to have a typo. They claim 72% which actually looks like the BM speed) Pulp density = 70% w/w; SAG feed is primary crushed to F 80 = 98 mm; Ball mill ...

design processing rates of the Cadia Hill SAG mill circuit and that could be easily manipulated were; SAG Mill Load Ball Charge - SAG mill power draw was guaranteed by the vendor at 13% ball charge and 30% total volume to be 20.96MW for the 40 foot diameter SAG mill. In practice this power draw was never achieved I-14 (Dunne et al 2001).

At the Cadia Valley Operations, Newcrest operates two underground mines and one open pit mine. Ore is processed to a heavily auriferous copper concentrate in a crushing, grinding and flotation circuit. This two-stage grinding circuit consists of a 40 ft SAG mill with a 20 MW Siemens gearless drive and two parallel 10 MW gear driven ball mills.

SAG mill drives (as GMDs) by some operators and principal motor designers/manufacturers until the reasons for known problems in design or manufacturing were better understood and resolved. Accordingly, the latest 40 ft dia. SAG mill is rated at 29 MW and 78% C.S., with a 42 ft dia. mill built but not yet operational. The more recent option
