Metso will deliver three grinding lines including spare parts and supervision to NLMK Group’s Stoilensky GOK iron ore production plant in southern Russia. NLMK has launched the construction of an additional concentration section including the three new grinding lines with Metso’s Vertimill. The lines will be assembled by 2020 in a single production unit and will enable scaling up the concentrate output with a 14% increase in capacity.

“The technique of using vertical mills to grind ore has been successfully applied at more than 100 iron ore mining and processing enterprises worldwide,” said Marat Mryasov, director, project management at Stoilensky GOK. “This technology at Stoilensky GOK will increase the efficiency of production processes and provide the necessary growth in the production of iron ore to enable the supply of cost-competitive raw materials to the Novolipetsk Metallurgical Combine, Russia’s largest steelmaking enterprise,”

“For today’s miners, saving energy and improving productivity while reducing costs are an integral part of building profitable business. When creating sustainable and resource-efficient processing solutions for our customers, we tap into Metso’s 150 years of global design and engineering expertise,” said Victor Tapia, President, Metso’s Mining Equipment business area.

Metso Vertimills are energy-efficient grinding machines with proven grind efficiency from varying feeds, from as coarse as 6 mm to products finer than 20 microns. In addition to reduced media consumption, the lower installation cost, minimal maintenance and minimal liner wear of the Vertimill make it one of the lowest total cost of ownership solution in many applications. Since its introduction in 1979, Metso has delivered over 440 Vertimills globally.
