Future-proofed and performing well
The upgrade process brought the two VPA units back to OEM specification and fully equipped them with the latest in Metso Outotec’s VPA technologies. This included an upgraded control system and HMI features that would future-proof the units in anticipation of further upgrades.
By resolving the continuing maintenance issues, and providing the latest technology, OTML now implements proactive and predictive maintenance for the filters, enabling reliable operations with the current set-up and into the future. Since the upgrade, Metso Outotec’s training and ongoing filter support have also helped with embedding the latest industry practices and procedures on-site.
Kiunga Operations Manager, Dexter Wagambie discussed the project and explained, “We were having plant reliability issues since the filter units were aging and the refurbishment project was timely.”
He said immediate results were visible since the completion of the refurbishment.
“These units are now processing 125 tons per hour with more than 24 hours’ slurry and no downtime. The units can produce 2,850 tons per day (tpd). Prior to the overhaul, we were averaging 2,152 tpd,” Dexter Wagambie said.
