Separate dry particles by size using less water

By Chemical Engineering |

This company has introduced a line of classifier systems (photo) that collect and separate dry particles by size range using only ambient air and gravity. Allowing the material to be kept dry upstream and downstream, these air-classifier systems eliminate the use of water, replacing wet processing with a dry-processing approach that conserves water. Settling ponds to manage wastewater and costly drying equipment for moisture removal upon delivery are also eliminated. Suitable for processing salt, potash, fertilizer, fly ash, alumina, manufactured sand, diatomaceous earth and a diverse variety of minerals, aggregates and other materials in continuous operation, the classifier line comprises three different models, based on classification method: a gravitational classifier; a gravitational-inertial classifier; and a centrifugal classifier. The classifiers may be used in series to split-feed multiple products at different cut points, and often include a cyclone or baghouse dust collector to meet pollution-control requirements. — Van Tongeren America LLC, Lebanon, Pa.
