Metso strengthen their position in Chinese grinding market

Metso Vertimill

Energy-saving vertical grinding mills are gradually replacing ball mills in comminution processes. An example of this development is Metso have signed their biggest ever order of this technology in China to Anshan Iron and Steel Group Corporation (Ansteel), one of the leading Chinese iron ore mining and steel making companies. The Metso equipment will be installed to Ansteel's Greenfield iron ore mining project, situated in Anshan, in the Liaoning province in China. The total value of the order exceeds EUR 33 million.

Pouris Huang, senior technical support engineer, Mining and Construction, Metso, commented: '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%.' 

Metso say that their Vertimill also provides benefits in grinding quality. 'With traditional ball mills it would be very hard to achieve the same ore fineness required by magnetic separation,' added Pouris Huang.

The contract includes six of Metso's biggest vertical grinding mills, six large mining cones and three vertical pressure filters, together with related installation and commission guidance services. Metso's delivery completion is due in March 2014, with the mine due to start up in July 2014. The order was included in Metso Mining and Construction's first and second quarter 2013 orders received.

'Last year, Metso successfully installed their first vertical grinding mill into a Chinese copper mine. The delivery was finalized in a record time - in just over 12 months, and the customer has achieved the planned grinding capacity and wear part economy.  This new Ansteel order, with its quick delivery time, will surely interest Chinese mining professionals country wide,' said Pouris Huang.

The six Vertimill VTM-1500-type vertical grinding mills are fed by an average rate of 653 tonnes/h. In addition to the mills, Metso's delivery consists of six HP800 cone crushers for secondary crushing, and three VPA2050-54 pressure filters for dewatering of the iron ore concentrate.
