2018-5-10 SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason, they have an important impact in energy consumption and in the operation of the power distribution system. Figure 1. Picture of a typical GMD system for a SAG mill Figure 2 presents the power circuit of a cycloconverter fed synchronous motor.
The installation of AG and SAG mills for comminution circuits has led to many economic advantages in mine site over the years , such as their high throughput and low maintenance. SAG mills are the largest tumbling mills used for primary grinding in mineral processing, using a coarse feed (typically up to 250 mm diameter rock) coming from a ...
Gross SAG mill power is measured at a meter and includes the drive train power loss. This is a practical method of measurement because most SAG mills have a synchronous motor coupled directly to the pinion. Electrical and mechanical efficiency loss is only about 6% in such installations.

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
Preliminary findings from this installation will be presented along with comparisons of generic information, such as toe position (measurement precision and operation variability) and vibration signal (intensity, sensitivity and operation variability), between this type of primary grinding mill and AG/SAG mills.

2010-4-13 Today, autogenous grinding (AG) mills as large as 40-ft in diameter with motor power in excess of 20 MW are being ordered and installed as producers look for higher production and economy of scale in their process plants. Semiautogenous grinding (SAG) mills up to 44-ft diameter with 35-MW gearless mill drives (GMDs) are available.
