includes an oversized SAG mill and gyratory crusher. For this expansion project, Kinross selected ABB to provide a 26 MW gearless mill drive system (GMD) for the mine's 40 ft SAG mill, as well as other drives, electrical infrastructure equipment and a long-term service agreement (LTSA). GMDs improve process throughput
Gearless mill drives As was mentioned above, a gearless mill drive constitutes both an important part, but also one of the most critical elements of a concentrator or a cement plant. Their purpose is to ensure the continuous rotation of specific types of tumbling mills, more specifically autogenous grinding (AG) mills, semi-
The first Gearless Mill Drive (GMD) with a power of 6.5 MW was installed 1969 in a cement milling process in the cement plant Le Havre in France. In the first few years, the GMD was only used in the cement industry. The GMD is also known as …

Building on over 130 years of experience in the mining industry, ABB's Ring Motor factory located in Galindo provides the engineering and manufacturing of ring motors, the main component of ABB's Gearless Mill Drive (GMD) systems manufactured by ABB for the mining sector. The 20,000 m2 plant manufactured over 110 motors delivered in over 25 …
mill from and a 28 Mega-Watt (MW) Gearless Mill Drive (GMD) from ABB for the Conga Project in Peru. The test and study work showed that a single line 42 ft SAG mill circuit gave the most favorable project economics in comparison to an equivalently powered single line 40 ft SAG mill circuit. This paper
Gearless mill drives (GMDs) constitute a compelling alternative to traditional ring-geared mill drives (RMDs) in such environments. Both drive types can be used to power large semi-autogenous (SAG), ball and autogenous mills, but GMDs are proven to offer superior availability, uptime and efficiency. When the first GMD was …

Conveyor systems are responsible for almost 80% of the energy consumption in mines. Gearboxes are maintenance-intensive and their lifetime is relatively short. ABB is removing the gearbox, replaced with a permanent magnet motor technology. Benefits are manifold: reduced maintenance and risk of failure, reduced energy consumption by 6-10%, +10 ...
Ring-geared mill drive system. High performance and flexibility in grinding. Decreasing global mineral resources, exploitation of lower ore grades in more remote locations and extreme environmental conditions lead to increased material processing and potential rise in CAPEX. The need for reliable and robust grinding solutions is driving the ...
The six ABB GMDs, which are the most powerful mill drive systems on the market are all now in continuous operation. Two 28 MW gearless mill drive systems (GMDs) are operating in the mine's 40 foot SAG mills and four 16.5 MW GMDS are employed in 26 football mills along with associated control systems.
