Paper held at SAG Conference 2011 By S. Gaulocher (ABB), Stadler (ABB), Th. von Hoff (ABB), R. Veldsman (ABB), A. Fuerst (ABB) and J. Koponen (ABB): Gearless mill drives (GMDs) are the workhorse in the mineral processing industries, more specifically when it comes to grinding crushed ore and cement (in various production stages) in semiautogenous (SAG) mills and large ball mills.

In future, the 36foot SAG mill of the new production line will be operated with a drive. A further gearless mill drive with 22 megawatt output will ensure equally efficient and reliable driving of a ball mill with an inner diameter of 28 foot. Gearless drive systems are distinguished by their high efficiency and their low ...

Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc and tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

In Systems for Gearless Mill Drives, SAG Conference, Vancouver. addition, the values measured, recorded and collected by supervision systems give valuable input to analyze the status and the condition of [2] Ahrens, M. and Gonser, J., 2006, Service and Maintenance for the drive system and its components and therefore to detect potential ...

Common convention generally refers to highaspect ratio mills as SAG mills (with diameter to effective grinding length ratios of 3:1 to 1:1), lowaspect ratio mills (generally, a mill with a significantly longer length than diameter) are also worth noting.

Semi Autogenous Grinding (SAG) Mill For Sale, Sag Mining | CIC Home Equipment Grinding Mill SAG Mill SAG Mill Semi autogenous mills or SAG mills as they are often called, can perform grinding operations equivalent to two or three stages of crushing and screening.

SAG mill and two 26 ft ball mills, all made by Metso. The drive systems that enable the mills to operate at benchmark levels of reliability, efficiency and availability were made by ABB, whose solution comprises a MW gearless mill drive (GMD) for the SAG mill, and two 13 MW lowspeed dualpinion ringgeared mill drive (RMD) systems for the ...

In 2010 Newmont made the decision to purchase a 42 foot (ft) SemiAutogenous Grinding (SAG) mill from Metso and a 28 MegaWatt (MW) Gearless Mill Drive (GMD) from ABB for the Conga Project in Peru.

Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...

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. FullerTraylor SAG/AG Mills range in size from through in diameter with powers as high as 28,000 kW.

We utilize 2 x 6500KW drive motors in parallel on our SAG mill. One of the world's largest geared drive configurations is in Wushan, China, where they use 2 x 8500KW motors.

In a largescale operation, feed ores are introduced into the AG/SAG mill in a continuous mode at a given flow rate to replace the discharging slurry. Nonetheless, the variations in the feed characteristics, typically hardness and size distribution, could cause sudden disruption to the mill operation. This would be challenging to detect in practice, owing to the hostile environment of the mill.
