#0183;#32;One of the largest SAG mills (12 m diameter), has a variable speed gearless mill drive (GMD) with a capability of 28 MW for refining copper molybdenumsilver, and the average power draw is around MW with a feed rate of up to 6000 t/h .
The world''s fst 42foot diameter 28 MW geless SAG mill The test and study work gave the most favorable MW GMD for a 40 ft mill for an iron ore project Read more. sag mill iron ore Coal Surface Mining SAMAC. sag mill iron ore processing Ring motor driven SAG mill for gold ore grinding.
SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. The largest SAG mill is 42'' in diameter, powered by a 28 MW (38,000 HP) motor AUTOGENOUS GRINDING MILL SAG .
SAG mills. And over the past three years the company has received ten orders for this type of mill, rated at up to 28 MW. In 2010, Siemens proudly announced the sales release of a 42foot gearless drive. The 42foot drive allows throughput to be nearly doubled compared to the 38foot mills
Gearless mill drive (GMD) technology has further expanded the use of large AG milling allowing to produce the world''s largest SAG mill of 42 in diameter drawing power at 28 MW. Today, is the world leading supplier of gearless AG mills operating globally.
ABB was awarded a multimillion contract to provide a 28 MW GMD for a 40 ft ( m) SAG mill and two 22 MW drives for a pair of 28 ft ( m) ball mills at Aktogay, and three identical systems at Bozshakol.
In addition, the contract includes the complete engineering and delivery of megawatt foot mounted GMD systems for the two 26foot ball mills. The 28 MW gearless motor will be manufactured in

SAG is an acronym for semiautogenous 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'' () in diameter, powered by a 28 MW (38,000 HP) motor.
Groundbreaking is one of the most recent orders, placed by Newmont Mining Corporation: As the first supplier in the market ABB won an engineering contract for a 28 megawatt GMD system for the first 42 feet SAG (semiautogenous) mill, the worlds largest mill in diameter.
has been selected to design and supply a 42ft x 25ft, ( x ) 28MW gearless SAG mill, plus two 26ft x 42ft, ( x ) ball mills and two VTM1500WB VERTIMILLS#174; for Newmont Minings Yanacocha Conga coppergold project in Peru.
1 x 28 MW GMD to power the 40 ft SAG mill; 2 x 22 MW GMDs to power two 28 ft ball mills ; The site''s altitude and high power system required ingenuity and flexibility when in came to engineering the three systems. Some of the changes compared to GMDs for lower altitudes were: N ew cooling system able to dissipate heat generated by the most
#0183;#32;An ABB ring motor can achieve an outer diameter of 24 meters, with a capacity of up to 28 MW. GMDs are typically installed in copper, gold and iron ore mines but can be applied for cement mills
