In June 1998, the world's largest grinding mill, the 40 ft ( m) diameter 20 MW Cadia gearless SAG mill, Power is supplied by a purposely built 132 kv overhead was commissioned. This was a leap of over 40% above line from Orange. the largest operating SAG mill.
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, servicefriendly and fit for purpose design to provide highest throughput, reliability and availability for your processing plant. eBook: Grinding transformation

ABB's scope of supply includes two GMD systems for 38 foot 23 mw SAG mills (Fig.) comprising transformers, ring motors and complete containerized electrical houses (ehouses). The variable speed drive solution allows for optimization of the grinding processes for ores with varying properties and different mill loads.
Another solution is to use the socalled "gearless drive." A cycloconverter reduces the power frequency and a synchronous motor is either wrapped around shell or mounted on a trunnion extension. This makes the mill essentially a part of a synchronous .motor rotor with the stator in its usual position around the rotor.
They all have in common a multiple of two to eight electric motors connected via a gearbox to the grinding table of the mill. Today three different designs are available on the market. 1) Multiple modular drive system ... GEARED VS GEARLESS DRIVE SOLUTIONS FOR GRINDING MILLS. Luis B. CVT Calculations. CVT Calculations.

GEARED VS GEARLESSDRIVE SOLUTIONS FOR GRINDING MILLS. Evaluating the merits of large geared mills versus gearless driven mills considering: Currently available systems in terms of power and mill diameter
Whether it is size or an installation at the highest altitude (4600 ), gearless mill drives (GMDs) are well positioned to contribute to the building of larger and ever more powerful mills. GMDs are the grinding solution of choice in challenging environments like high altitudes or varied climates in remote locations.
Grinding is a crucial process step in ore processing and for a mine's overall performance. That's why a grinding mill's gearless drive is the crucial piece of equipment in the concentrator and why it is subject to very rigorous demands. High availability and reliability throughout the entire lifecycle are a must, while unplanned
Current capabilities include inhouse design and manufacture of Grinding Mills up to m (45 ft) with 35 MW gearless drive and m (40 ft) 2 x 10 MW geared drives. Almost all the components are made inhouse (excluding the electrical motors) in one location.
