To meet the rising demand for sustainability, enhanced process adaptability and increased capacity, Metso has introduced Nordwheeler™ NW8HRC, a portable HRC 8™ crusher designed specifically for producing manufacturing sand. Read our export blog on how it can benefit your operations.

In crushed aggregates production, up to 30% (rock dependent) of materials gotten from the bedrock are reduced to sizes smaller than 4 mm, meaning they end up as waste. Transforming this non-saleable waste product into valuable resources is a persistent challenge for quarries worldwide. The scarcity of natural sand is also a global issue. HRC 8™, included in Metso's Planet Positive offering, has impressive energy efficiency, using up to 50% less power than other technologies while delivering equivalent net product volume.  

Jarno Pohja, Director of Portable Solutions within Metso's Aggregates business area, expresses pride in being the pioneering global aggregates equipment manufacturer to introduce a portable high-pressure grinding roll (HPGR) crusher for sand manufacturing. With Nordwheeler featuring HRC 8™, this crusher stands out as one of the most efficient options for producing manufactured sand, providing a sustainable alternative by replacing natural sand in concrete and asphalt production.

“The Nordwheeler NW8HRC crusher can be towed inside the pit and between quarries periodically for re-crushing waste piles," he explains. Nordwheeler portable plants are powered by electricity. On wheel-mounted chassis they are quick to setup without heavy concrete foundations. In many cases, a crushing permit is easier to get for a portable plant compared to a stationary plant.  

"Nordwheeler portable plants are equipped with the IC™ process control system. This intelligent automation maximizes crushing efficiency and enables complete remote control of the machines. Automatic process control enhances productivity, elevates product quality and ensures consistency in the final output,” Pohja continues.
