Metso Outotec says it will deliver several energy-efficient stirred mills to a greenfield iron ore processing plant in Liaoning Province, north-eastern China, marking one of its “Planet Positive” mineral processing orders.

The stirred mill installation, which corresponds to 11 MW of power, will be the largest of its kind in China, according to the OEM.

While the value of the delivery has not been disclosed, the order has been booked in the company’s Minerals segment September quartr orders received.

Christoph Hoetzel, Head of Grinding business line at Metso Outotec, said the company previously agreed on the delivery of a PG4265™ primary gyratory crusher and three HP900™ cone crushers for the same project, however the customer soon realised the benefits that could come with using its stirred mill technology.

“Our stirred milling technology, with its excellent performance and ability to increase both iron ore concentrate and recovery, has proven itself multiple times in the Chinese market,” he said. “The new installation will also benefit from class-leading energy efficiency and wear life.”

Metso Outotec claims to be the only manufacturer worldwide offering several stirred mill technologies (Vertimill®, HIG™ mill, and SMD).

The Metso Outotec Planet Positive portfolio focuses on the most environmentally efficient technologies – of which there are more than 100 – in the company’s current portfolio, responding to the sustainability requirements of its customers in the aggregates, mining and metals refining industries. The customer requirements relate to energy or water efficiency, reduction of emissions, circularity and safety, the company says.
