Turn waste material into saleable product
Turn waste material into saleable product

HRC equipment can convert quarry waste into a saleable product, reducing the pollution from earth moving equipment doing the double handling of those large volumes of waste materials. These machines are suitable for specific difficult applications where materials that are waste from the crushing and screening process (materials with low mass gradings, difficult to crush by a VSI or other types of compression crushers) can be reprocessed to obtain good high-quality saleable products. In some applications, the non-saleable waste materials can be processed by the HRC™ 8 or HRC™ 800 to correct the gradation curve and particle shape, converting them into high-value saleable products.

Handle challenging feed materials

HRC™ 8 and HRC™ 800 crushers work in applications where other crushers cannot. They can handle small in size and very difficult feed materials, that are difficult to process by any other technology, with high abrasiveness, low crushability, moisture, fines, even clay and turn them into a valuable product.


• Manufactured sand
• Gravel pits, pea gravel
• Asphalt sand
• Concrete sand
• Industrial minerals
• Recycling
• Re-crushing waste materials

These machines excel in manufacturing sand, meeting the growing demand for economical and efficient crushed sand production. As natural sand deposits dwindle and environmental regulations tighten, HRC™ 8 and HRC™ 800 offer a robust design, low operational costs, and superior product shape and gradation. The application is sustainable because it replaces the use of natural sand, reducing the need for loading and hauling natural sand into cities, which helps to avoid fuel burning and pollution. Furthermore, HRC equipment produces high-quality sand that reduces the demand for water and cement in concrete mixes, as well as in asphalt.
