Metso has won a contract to deliver 14 grinding mills to MMX mining company in Brazil. The value of the order has not been disclosed.
The mills will be assembled at the Serra Azul iron ore project, located in São Joaquim de Bicas, Brumadinho and Igarapé, in the state of Minas Gerais, south-eastern Brazil.
Once the new mills are assembled, the iron ore production capacity of MMX at Serra Azul will reach 24 million tons per year. MMX mining company’s power savings with Metso technology is expected to be about 18 MW in comparison with conventional ball milling.
— The Serra Azul project is a very important one as it consolidates the stirred milling technology in the iron ore regrinding applications, says Eduardo Kubric, Sales Director, Metso’s Mining and Construction, Brazil.
Metso says vertical grinding mills use 30 to 50 per cent less energy than a traditional ball mill while the machine has fewer moving parts which means lower maintenance and operating costs.
Since its introduction in late 1979, nearly 400 of the company’s VERTIMILL grinding mills have been sold worldwide.
MMX is a Brazilian mining company which belongs to EBX Group. The company operates two mines in Minas Gerais and Mato Grosso do Sul states in Brazil and also holds mineral rights in Chile.
