Cemtec and Siemens jointly developed a standard-equipment, economical solution to handle the power needed to drive a 10.4 x 6.1-m, 15-MW SAG mill and an 8.2 x 14-m 18-MW ball mill at this Russian gold mill site. Cemtec , an Austrian company, develops and executes projects for the mineral processing industry worldwide.
SAG (semi-autogenous grinding) mill with a 20 MW gearless drive designed by Siemens Drive Technolo-gies and two series-connected 10 MW gear-driven ball mills. The SAG mill was additionally fitted with the Sinamics SL 150 cycloconverter for motor con-trol and a Sinamics DCM power converter for con-trolling the excitation circuit.
Let us hope not because the original Collahuasi and Antamina SAG mill stators most likely would still be operating had they been wound with the type of VPI parallel windings used by Siemens. In this post, we review the new 24 h repair criterion proposed in [5] and how it applies to winding design.
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. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
Siemens, the company that introduced Gearless Mill Drives (GMD) to mining industry started up its first GMD on a ball mill in Norway in 1980. The mill and its drive system are still in service. Today, GMDs are mainly used for SAG mills between 36 and 40 feet (10.7 to 12.2 m) and ball mills from 24 to 28 feet (7.3 to 8.5 m).

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
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.

SAG mill drives (as GMDs) by some operators and principal motor designers/manufacturers until the reasons for known problems in design or manufacturing were better understood and resolved. Accordingly, the latest 40 ft dia. SAG mill is rated at 29 MW and 78% C.S., with a 42 ft dia. mill built but not yet operational. The more recent option
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
