ABB’s GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This ’workhorse’ for grinding operations combines a robust, service-friendly and fit for purpose design to provide highest throughput, reliability
The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record
The gearless mill drive eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
The company selected ABB's 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). This is expected to reduce operating costs, improve process throughput and reliability while saving energy and keep equipment in top form.
motor drive packages for hazardous areas As one of the few manufacturers that can offer drives and motors, it has long been possible for ABB to offer compliant motor drive packages under ATEX 2014/34/EU certification. The extensive range of motors on offer for these packages has been increased to include IE3 efficiency rated motors, bringing lower energy usage to the ATEX arena. The drive
It is a drive system without any gear where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. The concept to drive the mill this way is relatively simple using the mill body as motor
ABB’s new Gearless Mill Drive generation: Maintenance-friendly features raise availability and productivity Axel Fuerst, Reinhold A. Errath, Sebastian Gaulocher ABB, Switzerland Luis Arana Yanacocha, Peru ABSTRACT This paper presents modifications made to the motor design and concentrates on those points that have reduced, simplified and shortened the motor maintenance such that motor
The DriveConfig kit is a new drive configuration tool for ABB component drives, ACS55, offering fast and safe configuration of unpowered drives. DriveBrowser for monitoring and tuning low voltage general machinery, standard, and industrial drives over Ethernet network.
The drive works seamlessly with all motor types and includes excellent tuning possibilities for the quietest, safest, most efficient and most comfortable passenger experience without vibration and jerks. Low power consumption helps you fulfill the latest energy efficiency classifications, and selecting a regenerative drive option lets you reduce the elevator's carbon footprint and operating
ABB’s gearless conveyor drives (GCD) enable the design and construction of high torque conveyors which go to the limit of belt strengths and pulleys. Synchronous motors (2.5 9MW, 50-60rpm / 400 1700kNm) are embedded onto a special base frame which allows to transport the motor in a piece, to perform shortest installation time as well as quick and easy alignment of the motor to the pulley

other mill automation. PMC800 drive system is designed to reduce the cost of ownership over the automation lifecycle and improve energy efficiency during production. Used on paper machines for control, drive units and motors, ABB Drive Systems have been installed in more than 3,000 mills worldwide. Consistent and repeatable ABB’s PMC800 drives are engineered for performance,
Instability in gearless mill drive motors by Peter Warner, Anglo American Technical Division In 2006 Anglo Platinum ordered two 26-foot ball mills from FFE Minerals Vecor and two 17,5 MW gearless mill drives (GMDs) from ABB for the 600 kilo tonne per month concentrator for the Potgietersrust Platinum North expansion project. the stator and the rotor. Since very large radial magnetic forces

plied gearless drives for two 36-foot ring motors, de-veloping a 12,000 kW gearless drive for the Kennecott, Utah, SAG mill and a 11,200 kW gearless drive for the El Teniente, Chile, SAG mill. In a continued call for larger, even more powerful drives, Siemens kept pace. In 1996, Freeport ordered the first gearless drive for a 38-foot SAG mill located at the company’s Grasberg plant in
