Metso Outotec says it has signed a services contract for the delivery of four ball mill upgrade packages to a copper and gold mine in Asia Pacific, which has a value of €19 million ($21.4 million).

Refurbishment projects for older, existing assets are an efficient method to extend a mill’s operating life, increase energy efficiency and minimise waste and plant downtime, Metso Outotec said. Additionally, equipment refurbishments lead to improved machine availability and safety by delivering the latest available technology.

Jonathan Allen, Senior Vice President, Grinding, Bulk and Pyro business line of Metso Outotec, said: “We are pleased to have been chosen as the supplier for the grinding mill refurbishment project. The customer’s performance objectives were achieved by offering a technical solution which increased the operating volume of the mill and allows for future process optimisation. Providing these 30-plus-year-old mills a new lease of life is exciting for Metso Outotec and builds on our sustainability promise of delivering circular offerings.”

Metso Outotec says it has delivered and serviced over 8,000 grinding mills globally, including some of the largest and most powerful mills in the world.
