SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but 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.
moreThe SAG Mill is a block added by the EnderIO mod. A machine similar to a Pulverizer or a Macerator. It is used to process resources to produce dust. It accepts energy in the form of Redstone Flux or Minecraft Joule, with an internal buffer of 100,000 RF and consumption of 20 RF per tick.
moreSAG mill ball charge determination and its influence on mill drive requirements Abstract: In semi-autogenous grinding (SAG), the grinding mill inventory, (i.e. volume of total charge, volume of ball charge, etc.) is important in determining the optimum operating condition for maximum production (tph), minimum specific energy (kwh/t) or lowest ...
