SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
terms such as "SAG mill inefficiency factor." As ore breakage characteristics can be a major factor in AG/SAG mill product size distribution, Figure 2 compares only data for porphyry ores. Before the true power efficiency of an AG/SAG grinding mill can be properly assessed by using the Wio concept, the T 80 used for calculations must be

The SAG mill cracked through the flange and into the shell and this threatened the integrity of the mill. ... Siemens have now adopted the four-pair rib design for all their new motors [11]. The changes made to the ABB hanger plates were part of a wide range of changes made to the design since 2006.
SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.
