Driving value

The latest generation of ABB medium-voltage frequency converters provides excellent opportunities to improve the grinding process used in the minerals industry. Thanks to the development of several dedicated and advanced operational functions for the ring-geared grinding mills used in the industry, this generation of drives ensures smooth, safe and reliable operation with minimum stress on the mechanical equipment, as well as the highest possible availability of the mill. Part one of this two-part series will explains the operational benefits of implementing these functions, while part two will focus on the practical experiences gained with this kind of sophisticated ring-geared mill drive system.
