Metso has signed a contract with Brazilian mining company MMX Mineração to deliver 14 vertical grinding mills needed for the expansion of the Serra Azul iron ore project in Minas Gerais, southeastern Brazil.

Installation of the VTM-3000-WB Vertimills, each powered by 2,235-kW drives, is a significant element in MMX’s program to boost production capacity at Serra Azul to 24 million mt/y. According to Metso, the Vertimill technology also will provide significant power savings compared with conventional ball milling.

MMX, part of the EBX Group, operates mines in Minas Gerais and Mato Grosso do Sul states in Brazil and also holds mineral rights in Chile.
