Energy-saving vertical grinding mills are gradually replacing ball mills in comminution processes, says
The total value of the order exceeds €33 million.
The Metso equipment will be installed to Ansteel's greenfield iron ore mining project, Anshan, Liaoning province in China.
“In applications like Ansteel, Metso's vertical grinding mills provide the right solution for the customer. The mills can generate energy and wear part savings of at least 35%," says Pouris Huang, senior technical support engineer, Mining and Construction, Metso.
Metso Vertimill is also said to offer benefits in grinding quality.
“With traditional ball mills, it would be very hard to achieve the same ore fineness required by magnetic separation,” adds.
The recent contract includes six of Metso's biggest vertical grinding mills. In addition, six big mining cones and three vertical pressure filters and related installation and commission guidance services. Metso's delivery completion is due in March 2014, and the mine start-up in July 2014. The order was included in Metso Mining and Construction's first and second quarter 2013 orders received.
The six vertimill VTM-1500-type vertical grinding mills are fed by an average rate of 653tonnes/hour, and in addition to the mills, Metso's delivery consists of six proven HP800 cone crushers for secondary crushing, and three VPA2050-54 pressure filters for dewatering of the iron ore concentrate.
