Portable crusher launched for manufactured sand

Metso has expanded its Nordwheeler NW Rapid range, introducing the NW8HRC – the first portable HRC 8 crusher for manufactured sand

Metso says it has expanded its Nordwheeler NW Rapid range to meet the growing demand for sustainability, process flexibility and higher capacity.

“We are proud to be the first global aggregates equipment manufacturer to launch a portable high pressure grinding roll [HPGR] crusher for sand manufacturing,” Metso aggregates business area senior vice president Renaud Lapointe says.

“Nordwheeler with HRC 8 is one of the most efficient crushers for producing manufactured sand, offering a more sustainable solution since manufactured sand can be used to replace the scarce natural sand in concrete production.”

Providing a sustainable option, Metso says the new machine consumes up to 50 per cent less power than any other technology in the same application to obtain the same net product volume.

“The HRC crusher can convert quarry waste into a sellable product. Further, the HRC crusher produces excellent quality sand that can substitute natural sand from natural deposits,” Lapointe says.

“Now on a wheel-mounted chassis, the HRC can be relocated within the site or towed to a new crushing plant for re-crushing the waste piles.”

Powered by electricity, the Nordwheeler portable plants can be set up without heavy concrete foundations, Metso says.

Metso says in many countries, the ability to relocate the entire plant means that it is easier to get crushing permits, which makes the plants a desirable choice for one to two-year periodical crushing projects.

This makes the plants useful in the construction of dams, airports and roads.

In addition to the NW8HRC, Nordwheeler NW Rapid range is expanding with five new portable crushers – NW300GP, NW300HP, NW330GP, NW7150 and NW9100.

Designed on Metso’s Nordberg and Barmac crusher technologies, Metso says these models are effective in secondary and tertiary crushing.

All new portable crushers are designed to fit in standard transportation dimensions, according to Metso, making towing them to a new site easier.

The company says they are quick to set up with on-board equipment and hydraulic options.

“Our new models feature a crusher without an integrated screen on the same chassis, which increases the flexibility of plant design and makes it easier for aggregate producers to adapt to changing end-product requirements,” Metso portable solutions director of the aggregates business area Jarno Pohja says.

“The Nordwheeler portable plants also feature IC process control system. Intelligent automation optimises crushing efficiency and offers the ability for full remote control of the machines.

“Automatic process control increases productivity, improves quality and adds consistency to the end product.”

Metso says the new units offer up to 500 tons (453.6 tonnes) per hour capacity, making the Nordwheeler portable plants available also for aggregate producers and contractors handling higher volumes.
