Metso unveils cost-cutting minerals processing technology

Metso's new rock crusher

Metso has launched a new rock crushing technology, which it says cuts operational costs by 10 per cent and enables 10 per cent higher uptime compared to traditional cone crushers.

The Metso MX, unveiled at the Conexpo-Con/Agg event in Las Vegas yesterday, is based on the patented multi-action crushing technology, which combines the piston and rotating bowl into a single crusher.

Designed for the most demanding rock conditions and with a special focus on automated adjustment features, the Metso MX enables cost effective and safe operations, the company explained.

It also provides a high reduction ratio with a premium end-product shape and consistency critical in aggregate applications.

“Aggregate producers are facing increasing pressure on efficiency and cost management,” Metso vice-president, global sales and product support Jouni Mahonen said.

“In order to meet these demands, we rethought the crushing basics and combined our long experience in different cone crusher technologies with our extensive engineering knowledge.

“Two individual crushing methods based on the piston and rotating bowl were conjoined, and as a result, we created the MX cone with multi-action technology.”

According to Metso, the key benefit of the patented multi-action technology is the easy under-load setting adjustment and wear compensation without having to stop the process.

This can be now combined with extended wear life and better mechanical protection. Optimal cavity design, stroke direction and effectively distributed 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, Metso added.

The Metso MX also provides maximised tramp release distance with high protection against uncrushable objects and overloading. The crusher can utilise up to 70 per cent of the mass of new wear parts.

“After 10,000 hours of rigorous testing, we are proud to say the Metso MX meets our targets for increased profitability by allowing 24/7 crushing with minimum downtime,” Mahonen concluded.
