Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach When future tonnage is to be increased the SAG Mill can feed downstream ball milling to boost capacity FullerTraylor SAGAG Mills range in size from 43m through 122m in ...
SAG mill. SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' () in diameter, powered by a .

SAG Mill Control: It Shouldn't be that Hard E MJ. While many mills today are mounted on load cells, others employ bearing oil pressure as a proxy measurement of mill load A control strategy recently implemented on a large variablespeed SAG mill at MMG's Century Zinc operation in Australia is shown in the chart (found on pg 32)
If the derivatives with respect to time of the power and bearingpressure signals have the same sign, the volume ofthe mill load is smaller than the optimum value; ifthey have different signs, the ...

In the light of increasing interest in that technology various ...
A new large concentrator unit typically consists of a semiautogenous grinding mill, high pressure grinding rolls, two ball mills, and a flotation circuit. It can treat up to 170 000 tonnes of ore per day Sartain, 2010). Larger concentrators consist of multiples of this basic concentrating unit. Smelters are almost always large because their minimum economic output is that of a single, fully ...

Modelling SAG milling power and specific energy . Jan 01, 2015 Even if the mill total load is a key variable and can be indirectly measured with bearing pressure measurements, it was decided to discard it as an input variable The case study mills have all the same discharge system, resulting in a lower variation in the effect of the slurry pooling on power SAG mill specific energy consumption (Ecs
· Increased bearing pressure should translate to a higher charge toe loion the more the mill is filled, the heavier it gets. Because of ore size, we should see noise above and below the ...

So if SAG mill bearing pressure is at 600 and the feed rate is increased 50 t/h, the dynamic response will be very different than the response if the bearing pressure had been at 700. The concept of complex means that once a series of system changes are made, reversing those changes does not return you to the same place you originally started . project manager. KnowledgeScape. SAG mill feed is ...
