14th AusIMM Mill Operators' Conference 2018, 29-31 August, Brisbane. ABSTRACT. The Concentrator 1 plant at Cadia transitioned from Cadia Hill open pit to the Cadia East block cave ore body in 2013. As a result of this change, major plant upgrades were required to achieve the desired throughput while treating more competent ore.

It is suggested that the standard adopted is the '40 ft SAG mill' at Cadia Hill (Figure 4). The reasons for this choice are that it is a large mill, it treats reasonably competent ore and has much ...

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 work led on to foundation analysis work at North Parkes and then Cadia Hill in 1996. The analysis of the Cadia SAG and ball mill foundations were critical in the resolution of the stator vibration problem that arose during the commissioning of the 40 ft SAG mill in 1998.

foot SAG mill at the Cadia Hill Mine in Australia. While the details vary, there is a theme that links these projects – careful development and analysis, timely results and ultimately the delivery of reliable, efficient gearless drives. Since 1998, Siemens has been providing gearless drive systems for 40-foot SAG mills.

The model of the Cadia Hill SAG mill was based and derived from the pilot plant SAG (12% balls)/recycle crusher surveys. These were part of the second pilot campaign and were runs with two different load volumes of approximately 21% and 31%. The data from these tests were used to fit

A two-stage grinding process forms a part of the comminution circuit. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels.

Oct 02, 2014· The remedial design of the stator of the gearless mill drive (GMD) of the 40 ft SAG mill at Cadia Hill was the project that defined the success of EAnD and the careers of its two engineering managers, Bill Lai and Chris Meimaris.

Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.
