Increase throughput and capacity in SAG mills

Replacing traditional steel cast mill liners with new lightweight composite liners is another way to increase throughput of mills. Major gold and copper operations have already started doing this in mills up to 40’ Ø and seen an improvement in the slurry discharge of up to seven percent.

Throughput optimisation in milling circuits

SAG Mill Power. SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly non-linear and shift as the ore hardness, steel load and liner conditions change.

Increase throughput and capacity in SAG mills

SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear the sound of the mills standing still.

Maximizing profits with fragmentation analysis

• Increase SAG mill throughput The Solution The operations implemented the Split-ShovelCam, Split-TruckCam and Split-ShovelCam to measure the rock fragmentation from post-blast product to the SAG mill feed. Blast designs were adjusted to measure the changes in rock fragmentation, equipment efficiency, mill efficiency and throughput.

Semi-autogenous grinding (SAG) mill liner design and

with increasing mill speed as shell lifters wear, is a promising current development in shell liner design and SAG mill opera-tion providing the potential for lower energy consumption, increased throughput, and start-up “on-grind” with new lifters (Veloo et al., 2006b). Highly worn shell lifters can still deliver adequate (though

autogenous (SAG) mill. The primary objective was to maintain an on spec and stable grinding product to leaching while maximizing throughput. This was achieved by leaching feed slurry while striving to maximize throughput. Leach feed stability was achieved by standardizing operating practices across shifts; a result of successful

INCREASING SAG MILL CAPACITY AT THE COPPER

Copper Mountain first feed to the SAG mill occurred in late May, 2011. The circuit began ramp up in mid-June of that year, with more consistent operating run times on the SAG and Ball mills. Plant throughput in the first months was quite variable with throughput tonnage greater than 40,000 tons one day and less than 25,000 the next on some

Changing sag mill liners type from Hi-Low to Hi-Hi at

Changing sag mill liners type from Hi-Low to Hi-Hi at Sarcheshmeh designing the liner profiles to maximize liner life inevitably reduces the grinding rate in the mill [2, 3]. It is, therefore, necessary to develop a balance in the throughput and reduction in the power draw based on the historical data for an operational 32 foot mill [4
