the mill gear in inching mode N o_mill is the actual output speed of the mill gear in normal running mode P mill_motor is the actual power of the main drive motor or 2 x main drive motor for dual pinion drives. The power computed above is considered P inch = N o_inch · P mill_motor N o_mill
Dual grease purged fluoroelastomer seals were included for long life and, The steel mill had gearbox failure on a large BOF drive that became frozen due to rust,, confidence with a stronger, more reliable SAG mill replacement gear, Horsburgh & Scott identified an input worm gear pinion and worm gear that were out of.
The dual pinion mill drive is a variable speed technology which will effect low mechanical stress impact on the pinion and ring gear by realising precise load sharing between the two motors of each mill. "ABB's mill solutions reduce energy consumption, reduce mechanical stress, improve the service life of equipment, and boost operational ...
Mill load sharing – Maintains equal torques on dual pinion mills throughout the whole speed range. Controlled rollback – Prevents backlash and reduces downtime. Mill power ride through – Keeps the mill operating even under …
Dual pinion high-speed mill drive (with gearbox) and dual-pinion low-speed mill drive (without gearbox). By using the latest generation medium voltage frequency converter drives of ABB as shown in figure 2, with exclusive DTC (direct torque control) technology, these demands can not only be reached, but even exceeded.
design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings.

TITAN BALL MILLS. Based on the MPT TITAN™ design, the Mills are girth gear & dual pinion driven with self-aligned flanged motors, running on hydrodynamic oil lubricated bearings. The TITAN design enables you to run full process load & 40% Ball charge at 80% critical speed – Max grinding power for every shell size. Standard Mill Types Available:
Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...

MW). It has been the industry standard for SAG mills above 13 MW capacity. However, 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.
