Unlike a concentrator with multiple grinding lines, conducting SAG mill maintenance shuts down an entire concentrator, so there is a tremendous focus on minimizing required maintenance time; the reline timeline often represents the critical path of a shutdown (but typically does not dominate a shutdown in terms of total maintenance effort).

The Problem . Our client experienced a significant water and debris contamination event in the Fixed Bearing circuit of the SAG Mill. The mill was immediately shut down to avoid bearing damage and the contaminated oil was removed and new then oil introduced.

11.40 Multi-component AG/SAG mill model 1 $ M.P. Bueno, F. Shi, T. Kojovic and M.S. Powell (JKMRC, Australia) The JKMRC has been studying and modelling industrial AG and SAG mill for over 30 years, but the ability to simulate the effects of blending hard and soft components in mill performance is still quite limited.

So we've got the concentrator here, the gravity concentrator underneath the screen, feeds coming on. It needs to go through the screen to get to the concentrator, but if we're just tossing gold particles over and they're bypassing the concentrator, you're not even going to get a chance at them. So for a couple reasons, 1) screen ...

withdraw coarse ore from the bottom of the Ray concentrator coarse ore stockpile. The SAG mill feed conveyor transfers the crushed ore into the SAG mill for grinding. The SAG mill reduces the ore size to the consistency of coarse gravel, using a wet-grinding process. Discharge from the SAG mill is significantly wet and has the consistency of ...

The mill has been shut down while engineers on site work to determine the repairs required. Concentrator 2 SAG mill continues to operate at full capacity. While concentrator 1 SAG mill is offline, excess mine production from Cadia East is being stockpiled on surface which will then be processed later in the financial year.

Cadia Concentrator 1 SAG mill remains offline As communicated in the September 2015 Quarterly Report, on Saturday 18 October 2015 a problem was detected with the motor on concentrator 1 SAG mill. The mill was taken offline for inspection by engineers. The inspection has revealed more loose windings than initially anticipated.

Changes in metal prices and mine output over recent years have required the Copper Concentrator of Mount Isa Mines to operate at annual tonnage rates varying from 4.0 million to 6.5 million tonnes. Several circuit combinations were operated during this period utilising up to two semi-autogenous grinding (SAG) mills and up to two ball mills. The aim was to maximise …

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.

In 2007, the first modernization phase commenced. The initial phase included the construction of a 34 foot semi-autogenous grinding (SAG) mill, conversion of rod mills to ball mills and the complete replacement of the flotation recovery system with 160m3 float cells, along with the addition of new mining equipment.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
