feature CRUSHING, SCREENING AND MILLING The Metso MX™ cone crusher features Metso’s Multi-Action crushing technology.

Metso pushes the boundaries

New developments fromMetso in the crushing field include the Metso MX™ cone crusher, described as an “industry changer”, and the addition of high pressure grinding rolls (HPGR) technology to the group’s portfo- lio, a development which has taken place over several years and which has seen the world’s largest HPGR being installed at a copper mine in the US.

T he Metso MX™ cone crush- er was introduced at the CONEXPO-CON/AGG show in Las Vegas in March this year. It is based on Metso’s patented Multi-Action crushing technology, which combines the piston and rotating bowl into a single crusher. According to Metso, it “provides a giant leap in profitability by cutting operational costs 10 % and enabling 10 % higher uptime compared to traditional cone crushers.” The key benefit of the Multi-Action tech- nology is that it allows easy under-load setting adjustment and wear compensation without

having to stop the process. Optimal cavity design, stroke direction and effectively dis- tributed crushing action lead to the ultimate rock-on-rock crushing motion. This combined with the innovative Multi-Action technology results in extended maintenance intervals and higher production. The Metso MX™ also provides maximised tramp release distance with high protection against uncrushable objects and overloading.
