Your unused or rejected aggregate materials can be turned into profitable product with the help of reliable and robust technologies. Metso offers complete crushing and separation solutions for greenfield sites as well as solutions that can be incorporated into existing plants for sand making.
Turn waste stockpiles into profitable product
Manufacturing sand from waste stockpiles is an ideal way to produce a high-quality commercial product that has a market and high demand
Extensive engineering and process competence
High quality product and reliable equipment with guaranteed performances
High pressure grinding roll HRC™ 8
Metso HRC™ 8 is one of the best solution for this purpose with more than 120 units sold. Thanks to its energy efficiency and the ability to process waste streams this product is part of Metso’s planet positive portfolio. The HRC 8 and HRC 800 offer efficient crushing for tough materials with low crushability, moisture, clay, and high fines content, without causing packing or overload. These models produce top-quality products with
improved shape, low energy consumption, and minimal wear parts cost. They excel in manufactured sand and recycling applications, offering the lowest cost per ton. The HRC 8 and HRC 800 provide easily adjustable
product gradation.
Cone crushing technology - High energy efficiency and capacity
When you produce sand, you need high energy efficiency, high capacity, good product gradation, a high reduction ratio and low sensitivity to rock hardness. Metso cone crushing technology meets all these requirements. Metso’s advanced highspeed cones have high crushing forces, while the cavity design ensures that crushing occurs along the full length of the crusher cavity within multiple crushing zones. This guarantees inter-particle crushing and efficient production of the required fines and cubically shaped products. Our technology and know-how give you the opportunity to produce well-graded and shaped.
VSI crushing technology - High energy efficiency and capacity
For customers who need to process fine, unscalped, heterogeneous or irregular feeds, Metso offers vertical shaft impact (VSI) crushing technology. Unlike cone crushing, with VSI technology shaping is not influenced by the closed side setting (CSS), and shaping occurs throughout the product curve. With rock-on-rock crushing you can produce sand that is well known for its cubical shape and consistent gradation, and which has proven performance in concrete and mortar products. With VSI technology the gradation and quality of the product does not tail off with increased wear on parts. This allows you to reliably produce the right grades of sand to ensure the best performance.
Air classification technology - Dry classification with a gravitational inertial classifier
As a sand producer you need an effective way to classify your products. The global trend is to utilize dry classification solutions to separate fine and coarse particles. With Metso air classification technology you can reduce the percentage of superfines in your manufactured sand, enabling you to meet your specifications and produce high-quality products. Air classification is a simple technology as it removes the need for slurry treatment or ponds as well as dewatering. The technology also works in cold climates.
