The trend to larger grinding mills with the attendant increase in motor drive horsepower has affected the options for drive equipment. Also the development of large adjustable speed drives has created new possibilities for mill drives. Grinding mill torque characteristics, drive requirements, and torsional excitations of the various types of available drives will be briefly reviewed.
Gearless motors up to 22 MW are in service in many of these ore processing plants. Gearless motor drives are also known as ring motors or wrap around motors. The motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill. This is similar to the rotor of a conventional motor.

ABBs 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, servicefriendly and fit for purpose design to provide highest throughput, reliability
Oct 29, 2019#0183;#32;Two 28 MW gearless mill drive systems (GMDS) are operating in the mines 12metre SAG mills and four MW GMDS are employed in 26 ball mills along with associated control systems. Gearless mill drives are the workhorses for grinding operations which are at the heart of any mine.
Evaluation of synchronous motors on grinding mills. April 2014; DOI: / The subject of this paper is a synchronous drive of grinding ball mills 4 MW,
Motor The GMD 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 rotor and mounting the poles there.

after which everything is ready to drive the mill. Once the variable speed solution is chosen, an important decision to be made by the operator is left referring to the motor: whether to opt for a high speed or low speed solution. Gear driven mills can be motorized both with the high speed solution or the low speed solution.

1). A 2 pole (3600 RPM) motor with a 4quot; drive wheel will produce a surface speed of about 3700 sfm. 2). A 4 pole (1800 RPM) motor with a 6quot; drive wheel will produce a surface speed of about 2800 sfm. This is why 6 and 8 pole motors are not very useful without some countershaft ratio to up the speed.
Evaluation of synchronous motors on grinding mills Abstract: Synchronous motors continue to be a viable alternative to induction motors because of efficiency advantages. Long used for providing leading kVARs for PF improvement and helping with the device switching in Load Commutated Inverter (LCI) drives, these machines are efficient prime movers for large Mill applications.

behavior of large Ring Motors for grinding mills 3 1 Introduction The mining industry uses grinding mills to comminute tonnage. Large grinding mills are driven by Gearless Drives, with the Ring Motor as its main component. The Ring Motor is wrapped around the mill and its rotor poles installed at an extension of the mill head.
