SAG Ball Feeder Mill, Lihir
Lihir, Papua New Guinea

Project Details

Located in the New Ireland Province of Lihir in Papua New Guinea, CE Group executed Electrical and Instrumentation works on the Semi Autogenous Grinding Mill’s Ball Feeder project.

This project automated the addition of grinding media to the HGO1, HGO2 & FGO SAG mills to enable a consistent ball charge to be maintained within each mill, maximising grinding circuit throughput and ultimately increasing efficiency of the operation. In conjunction with risk reduction in manual handling labour, the project introduced innovations and technology not seen in the region, and continued rollout of initiatives from other Newcrest mine sites. The project reflects Newcrest’s Safety and Sustainability, Operating Performance and Technology and Innovation pillars, making work easier and safer, increases productivity and provides an optimum ball charge to the grinding mills for increased ore processing tonnage.

CE Group continues to engage national electrical employees for our works in the region, ensuring the sustainability of electrical labour in country.
