ABB launches new system to increase grinding roller duration in mining
Published: Friday, 11 December 2015
HPGR technology is used in a number of mineral sectors such as limestone and in hard rock industries. However rollers are prone to different rates of wear, resulting in a premature replacement – an issue that ABB has sought to address.
Automation technology group ABB has launched a new control
system to improve high-pressure grinding roller (HPGR)
performance and duration in mining.
Based on real-time load sharing between the rollers, the
RollXtend system allows the operator to manage the torques
delivered by each roller. Speed match is also maintained with
