Metso has expanded its Nordwheel NW Rapid range with the new NW8HRD portable crusher. Metso says that the new portable crusher release responds to the growing demand for sustainability, process flexibility, and higher capacity. The NW8HRC is a portable HRC 8 crusher for manufactured sand.
"We are proud to be the first global aggregates equipment manufacturer to launch a portable high-pressure grinding roll (HPGR) crusher for sand manufacturing. 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," says Renaud Lapointe, senior vice president of Metso products in the aggregates business area.
HRC 8 is a part of Metso's Planet Positive offering. It consumes up to 50 percent 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 continues. "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."
Nordwheeler portable plants are powered by electricity, 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 one to two years periodical crushing projects.
In addition to NW8HRC, the Nordwheeler NW Rapid range is expanding with five new portable crushers. The models are designed on the Nordberg and Barmac crusher technologies for secondary and tertiary crushing. The new models are NW300GP, NW300HP, NW330GP, NW7150, and NW9100. All the new portable crushers are designed to fit in standard transportation dimensions, making towing them to a new site easy. They are quick to set up at the site 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", says Jarno Pohja, director of portable solutions for the 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. Automatic process control increases productivity, improves quality, and adds consistency to the end product."
The new units offer up to 500 tons per hour capacity.
