We provide optimized mill drive solutions for all types of ring-geared mills: low and high speed, single and dual pinion, with and without a gearbox — all designed for …
Gearless AG/SAG mills . Variable speed capability Removal of limits of design power gear and pinion drives are practically limited to about 10,000 hp per pinion. at this time, there is no reasonable gear drive alternative for more than two pinions or above 20,000 hp. the best solution is the gearless mill.

Mills are one of the biggest energy consumers in a mine. Controlling them with variable speed drives results in significant energy savings. The ACS 1000 variable speed drive system consumes 310,786 kilowatt hours (kWh) per month (672 operating hours) less than the old system. Multiplying it with the price of A$ 0.05 per kWh results in monthly energy savings of A$ 15,540 (US$ 16,881). Optimized ...
An ABB solution – the most powerful of its kind in the world – is enabling the highly energy-intensive ore-grinding process at Australia's largest gold mine to set benchmark levels of energy efficiency, productivity, process flexibility and displaced CO2 emissions.
Advancements in drive technology, careful selection of the hardware and power system configuration, and intelligent motor control strategies produce improved operating performance, control capability and …
Milling is a cutting process that uses a milling cutter to remove material from the surface of a workpiece. The milling cutter is a rotary cutting tool, often with multiple cutting points.
The new COPE gearbox contributes the feature of working without variable speed drive and also operating with a reduced number of motors. This means the new drive concept allows for operation with, for example, 7, 6 or only 4 of the available motors. Even in operation with only 7 …
Based on analysing classical drum and tubular ball mills with a fixed structure, biconical and stage-type mills with a rigidly-variable structure, and mills with a variable speed electric drive, and advanced grinding concept has been suggested in the October 2009 issue of World Cement (pps. 67-78).
A key part of the process is the ultra-powerful ABB variable speed drive system that controls the four huge high pressure grinding rolls (HPGRs) that grind the rock into optimally sized pieces that can be fed to the ball mills for further processing into gold and copper.
