Accurate fines control for engineered sands

Quality specification engineered sands from crushed rock Evolving dry sand solutions Global growth equates to increased demand for dwindling natural sand resources. In many regions, the availability of natural sand is further impacted by a combination of increased environmental awareness, along with higher demand for land in sand-producing areas. Engineered sand solution Metso Air Classifiers give operators the ability to add significant value to the normally low value crushed rock fines by removing ultrafines to produce specification manufactured sand. This technology gives quarries the ability...

• ut point and retained ultrafines are fineC tuned to meet specifications • eparation requirements normally at 63µm, S 75µm or 150µm (#230, #200 or #100) • uitable for EN, ASTM, GOST, IS, JS and GB S specifications • mount of ultrafines retained in the A product is adjustable and normally in the range of 3% to 10% Classifying to specification Fine tuning your engineered sands The Metso Air Classifier has the ability to adjust the amount of ultrafines in the end product to meet the full range of sand requirements and regional specifications from anywhere in the world. The Metso Air Classifier...

Simplicity by design Efficient operation, accurate separation, no moving parts The Metso Gravitational Inertial (GI) Classifier is a highly versatile classifier with multiple applications in construction, mining, and industrial mineral sectors. The GI Classifier achieves high degrees of accuracy for separations from 300µm to 63µm (#50 to #230), making it ideal for precise engineered sand applications. Feed material is evenly distributed across the width of the unit before entering through an airlock The controlled curtain of material is allowed to free-fall into the chamber The system fan draws...

Control cost and accuracy Low operating cost and long life The secret to the low operating costs of the Metso Air Classifier stems from its intelligent design. It eliminates the need for moving parts and reduces power draw by effectively utilizing the air movement. No Moving Parts The Metso Air Classifier contains no moving wear parts. Unlike competitor air classifiers, the only purpose of the wear liners is to protect the classifier body so no adjustment for wear is required as all the work is done by the air. Other classifiers require their customers to make frequent adjustments when classifying...
