Sag Mill Design Calculations
Mill (grinding)
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 .

Jan 14, 2013 · 1/14/13 IEEE SagTen Tutorial Sagtension Calculations – Key Line Design Parameters • Maximum sag – minimum clearance to ground and other conductors must be maintained usually at high temp. • Maximum tension so that structures can be designed to withstand it.
Autogenous and SemiAutogenous Mills | FL
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 SAG/AG Mills range in size from through in diameter with powers as high as 28,000 kW.
A comparative
SAG mill power includes a correction for the interstitial mill filling. In the case of the estimated ball mill power, the power was calculated using the Bond methodology. Table 4 shows the principle parameters obtained. The 25th percentile throughput rate corresponds to the 75th percentile Axb value.
