Metso is expanding its Nordwheeler NW Rapid range with the new NW8HRC, the first portable HRC 8 crusher for manufactured sand.  

The HRC crusher can convert quarry waste into a sellable product that can substitute natural sand from natural deposits.

“We are proud to be the first global aggregates equipment manufacturer to launch a portable high pressure grinding roll (HPGR) crusher for sand manufacturing,” said Renaud Lapointe, Senior Vice President, Metso products of the Aggregates business area.  

“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.” 

HRC 8 is a part of Metso’s Planet Positive offering. It consumes up to 50 per cent less power than similar technology in the same application to obtain the same net product volume.  

Nordwheeler portable plants are electric, and they can be set up without heavy concrete foundations. 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 periodical crushing projects, such as the construction of dams, airports and roads.  

“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,” Lapointe said.

In addition to NW8HRC, Nordwheeler NW Rapid range is expanding with five new portable crushers. The models are designed on the proven Nordberg and Barmac crusher technologies for effective secondary and tertiary crushing. The new models are NW300GP, NW300HP, NW330GP, NW7150 and NW9100. All new portable crushers are designed to fit in standard transportation dimensions, simplifying towing them to a new site. At the site, 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”, said Jarno Pohja, Director, Portable Solutions, Aggregates business area at Metso.

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

As well, automatic process control increases productivity, improves quality and adds consistency to the end product,” he said. 

The new units offer up to 500 tons per hour capacity, making the Nordwheeler portable plants available also for aggregate producers and contractors handling higher volumes
