Ringgeared mill drives Grinding ABB
We provide optimized mill drive solutions for all types of ringgeared mills: low and high speed, single and dual pinion, with and without a gearbox — all designed for reliable, long life and low maintenance operation For both solutions, the conventional dual pinion mill drive systems have several significant disadvantages Therefore instead of just copying an existing and rather outdated technology, ABB’s target was to have a superior, but still competitive, dual pinion mill drive Paper # 25 Copper Mountain Overview on the Grinding ABB’s dual pinion mill drive systems provide real time frozen charge protection which is especially important for the operation of the ball mills Also its dual pinion drives solutions provide the option of variable speed, which enables the end user to increase the Dual pinion drive systems for Detour Gold’s new mine
ABB RingGeared Mill Drives
ABB ringgeared mill drive solutions offer a modular concept that provides a common drive control platform for induction and synchronous motors in single and dualpinion configurations These drives are wellsuited for all type of mills and ball mill applications, and dual pinion solutions were developed to power the mills However, realization of the dual pinion solution was only possible when load could be evenly shared between the two pinions When mill diameter and mill power became again increased, only the Gearless Mill Drive (GMD) could be envisaged to cover this requirement above 10 MWCMP Paper 161009 Final2 天前 GE rises to the challenge of building a world that works Learn how our dedicated team, leading technology, and global reach and capabilities help the world work more efficiently, reliably, and safelyGE Building a world that works General Electric
