SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of ...
pinion systems to 8 MW per pinion and dual motor systems with quadruple pinions extend the range of gear driven mills to a theoretical limit of 32 MW. The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia. Problems have been experienced with the twin pinion drive at Fimiston and with the ...
The SIMINE Gearless mill drives pump system significantly enhances concentrator productivity by eliminating the reducer gear between motor and pump and all corresponding maintenance. In addition, the cyclone pumps with variable speed can adjust their energy consumption to the optimized flow of pulp, resulting in energy savings of up to 30%.

DUAL PINION MILL DRIVES The SAG and the two ball mills are gear driven and Copper Mountain selected the sophisticated low speed dual pinion mill drives from ABB to drive these mills. Brief History Sophisticated Dual Pinion Mill Drive Technologies About five years ago, ABB was already the market leader for Gearless Mill Drives (GMD). ABB
SAG mill 32 ft. single drive The natural progression in gear/pinion mill drives: The QdX4TM Mill Drive provides the next step in the evolution of change in mill drive architecture, while allowing the system to be built with components that are within current manufacturing capabilities.

Ball Mill PINION SHAFT BEARINGS. Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.

If the mill requires approximately 6000 horsepower or less, it is possible to drive it with a single pinion. To date, however, economics has dictated that most mills over 3500 horsepower be driven with two pinions, using wound rotor motors driving thru speed reducers.
The mill drive system consists of the main mill motor, the main reduction gear box, mill pinion and girth gear. The mill is also equipped with a barring drive which is either connected to the main drive reduction unit or alternatively mounted at the back of the main motor. Refer to Figure 2 for a schematic of the mill drive …

In addition, the cyclone pumps with variable speed can adjust their energy consumption to the optimized flow of pulp, resulting in energy savings of up to 30%.
The Slip Energy Recovery Drive (S.E.R. Drive) is a technology well proven in the industry for large power motoring systems that allows precise motor speed control at the same time that recover the slip energy in the wound rotor induction motors (WRIM). The typical applications include SAG mill, AG mill and ball mill.
What's the Difference Between SAG Mill and Ball Mill. ... to achieve forced discharge mill. Slow transmission. The slow drive consists of a brake motor, a coupling, a planetary reducer and a claw-type clutch. The device is connected to a pinion shaft and is used for mill maintenance and replacement of liners. In addition, after the mill is ...
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
