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. The 40foot (40') SAG mill now receives a feed of predominantly high pressure grinding rolls (HPGR) product with a minor component of secondary ...

 · In the island state of Papua New Guinea, Ok Tedi Mining Limited (OTML) runs the copper and gold mine Ok Tedi. OTML's drive train infrastructure at the Ok Tedi mine is in excess of 30 years old. In order to ensure long term profitability, OTML is using Siemens technology to supply and install complete new variable speed drive trains for the two SemiAutogenous Grinding mills SAG 1 and .

Our SAG mill strategies automatically adjust feed rate, mill speed and water addition to reduce upsets, eliminate grindouts, protect liners/lifters, and increase tonnage . We maintain desired operating conditions by constantly monitoring bearing pressure, mill power, recycle pebbles, mill density, charge toe and mill acoustics, and can increase throughput by 36% !!!!! GrindingExpert™ isn ...

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...

SAG mill, AG mill, milling, HPGR, work index, pilot plant INTRODUCTION The resistance of ore samples to breakage (or hardness) is measured through grindability testing. Several grindability tests have been developed over the years for different appliions and each test has its own strengths and weaknesses. Grindability testing is a compromise between test cost and its deliverable(s). Because ...

As one of the machines widely used in mining, a semiautogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the discrete element method (DEM) is used to simulate the ...

The effect of liner wear on SAG mill performance has gained much attention in recent years. It is commonly observed that the three key performance criteria of SAG milling; throughput, power and product size all improve as the liner wears. The increase in throughput is generally ascribed to the increase in the grate apertures and the increase in mill volume due to the wear of these components ...

Gearless mill drives are a well established solution for grinding appliions in the minerals and mining industries. The paper describes the functionality and technical features of such drive systems as well as their advantages compared to other drive solutions. Due to the variable speed operation the grinding process can be optimized for ores with varying grinding properties.
