Get PriceSAG is an acronym for semi-autogenous 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' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

Get PriceYou can assume this is a weight-to-volume concentration. It makes calculations easier if you convert volume to liters, so use this conversion: 1 ounce = 0.03 liters. You have 0.09 liters of solution or 90 milliliters. Since water weighs 1 gram per milliliter, the weight of the sample is 90 grams.

[PDF]Get PriceDevelopment of SAG liners has always been of considerable interest to mill operators as liners significantly affect plant performance (throughput, grind size), material costs and plant downtime. Thus, operators commonly trial different liner shapes, profiles, and configurations.

Get PriceThe SAG Power Index (SPI) test (Starkey & Dobby, 1996) uses a benchscale SAG mill test to - determine the specific energy of an industrial SAG mill. The test is operated in closed circuit and the time required to grind the material to a P 80 of 1.7 mm is used to predict AG/SAG .

Get PriceExcept I can't seem to convert the Clear Class (Tinker's Construct) into sand using any machine I can come up with. NEI shows a "Crusher" can do it, but this is different than a "Rock Crusher". I don't know what mod "Crusher" is from. Clear Glass is not accepted as an input into Rock Crusher, Pulverizer, SAG mill.. not sure what else to try.

Get PriceAfter converting AG mills to SAG mills on the account of liner profile change, 31% increase in throughput (from 419 to 548 t/h) in addition to 4% decrease in the product size (from 516 to 496 μm) were realized which was a significant contribution to the plant performance improvement.

[PDF]Get PriceA Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...

Get Pricewas surprising that the Bond Rod Mill Wi average was 11.3 kWh/t. Since the ore is unusually soft, the Rod Mill Wi is probably irrelevant in determining required power for the SAG mill.
