Metso Outotec confirmed that next year it will deliver two of its Vertimill VTM-4500 stirred mills to an unnamed gold operation in Australia.
The units will be the first of their kind to be installed in the country.
The company said the value of the order is dependent upon the scope of delivery, but will range between EUR 10 to 15 million.
Vertimills, according to Metso Outotec, can manage feed sizes up to 6 mm and grinding to products less than 20 microns. It is available in standard sizes between 15 hp (11 kW) and 4,500 hp (3,352 kW).
“[It] provides the lowest total cost of ownership compared to other grinding mills in many applications thanks to its high energy efficiency, reduced media consumption, low installation cost as well as minimal liner wear and maintenance,” the company added.
Metso Outotec’s other mill technologies include the HIG mill and the SMD.
