Metso NW Rapid concept gains ground

Unique crushing and screening plant finding favour with quarry operators in emerging markets

IN the highly competitive aggregates market, Metso say their NW Rapid crushing and screening system, which was introduced a year ago, has been proven to take flexibility to a whole new level, helping aggregate producers to profit more from even smaller contracts than before and to change site locations more often.

The Metso NW Rapid is said to be the world’s first and only wheel-mounted crushing plant that fits into standard containers and can be set up for operation in less than 12 hours. In addition to fast installation, the NW Rapid can increase production capacity by as much as 30% and offer higher uptime, better safety and ease of use.

The NW Rapid’s high production capacity was one of the decisive factors when M/s M G Contractors Pvt Ltd in India were looking for a new plant.

‘The new Metso NW Rapid plant is a perfect fit for our growing needs for more eco-friendly, mobile and economical solutions. When looking at the available products in the market, we realized that the NW Rapid is a breakthrough in terms of application and quality. It is also backed by Metso’s good brand reputation and their service standards,’ said Udit Mittal, director of M/s M G Contractors Pvt Ltd.

‘With this purchase, we feel confident that our production efficiency will increase by as much as 30% compared with a traditional solution, and the 12-hour set-up time is extraordinary.’

Setting up a conventional portable crushing and screening plant normally takes at least a week and often requires preparations with foundations and other site conditions. In addition, equipment transportation can be difficult and require special arrangements.

The NW Rapid is the only compact wheel-mounted crushing plant on the market that fits compactly into standard 40ft containers, allowing it to be easily transported from one place to another by sea, rail or truck. Fast installation and dismantling is facilitated by hydraulically fine-adjustable support legs, hopper walls and screen lifting.

‘Cost-efficiency achieved by easy set-up and flexibility serves our customers in the emerging markets particularly well, since it is important to be able to swiftly move production to where the construction projects are situated,’ commented Julius Mäkelä, Metso product manager for Portable Solutions.

The NW Rapid series includes equipment for multiple aggregate production needs, such as portable jaw crushers and cone crushers, as well as horizontal- and vertical-shaft impactor plants. With these products, customers can set up multi-stage crushing and screening plants for high-quality end products as well as for ballast production.

The NW Rapid crushing and screening plant can be fed by excavator, wheel loader or dumptruck. Ready-made layouts cover screen feed and cone feed applications, with and without surge hoppers and field conveyors.

The increased capacity is mainly achieved by the Nordberg GP220 cone crusher and the new four-deck, dual-slope screen, allowing higher screening performance. The whole process can be precisely adjusted by a process control system.

‘The new Metso IC50C process control system forms a seamless combination between the primary crushing stage and the secondary crushing and screening stage of the plant. The whole process, including field conveyors, can be started and stopped with the push of a single button, making daily operations safe and easy,’ said Mr Mäkelä.

Moreover, the NW Rapid complies with European safety standards and can be issued with a CE marking.
