ABB’s GMD is the most powerfulmilldrive system in the market to power semiautogenous (SAG),balland autogenous (AG)mills, This ’workhorse’ for grindingoperationscombines a robust, service-friendly and fit for purpose design to provide highest throughput, reliability

To ensure profitableoperations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of low-grade deposits become necessary. More powerful and largermills, higherballcharges and demanding ambient conditions call for a strong partner for grinding solutions.

Ball millingis one of the few unitoperationthat improves with increasingmilldiameter. If acceptable results can be obtained with a 12” jar mil, then good result will certainly be obtained with a 72” diametermill. Of course there is the possibility of overmilling, obtaining a different particle size distribution or a need to change ...

CombineABB's variable-speed drive system with advanced process control -ABBAbility™ Expert Optimizer for grinding - to provide maximummillcontrol. It can be applied to new or existing AG, SAG andball mills, powered by either ring-gearedmilldrives (RMD) or gearlessmilldrives (GMD).

Aball millalso known as pebblemillor tumblingmillis amillingmachine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of themillvolume and its size depends on the feed andmillsize.
