New Air Classifier Systems Use Dry Processing Approach

Press Release Summary:

Van-Tongeren’s Air Classifier Systems are available in gravitational, gravitational-inertial and centrifugal models. Units are used in the separation of dry particles by size range using only ambient air and gravity. The classifiers are suitable for processing salt, potash, fertilizer, fly ash, alumina and manufactured sand. Gravitational and gravitational-inertial classifiers separate fines of less than 150 mesh to 150 µm and 300 µm to 36 µm respectively whereas the centrifugal classifier from 100 µm to 15 µm.

Process Equipment Manufacturer Unveils Line of Air Classifier Systems

Van Tongeren Classifiers Separate Dry Particles by Size, No Water, No Moving Parts

Lebanon, PA: Process equipment manufacturer Van Tongeren America, Lebanon, Pa. (, has unveiled a line of classifier systems 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, the Van Tongeren air classifier systems eliminate the use of water, replacing wet processing with an environmentally responsible, dry processing approach that conserves water. Settling ponds to manage wastewater and costly drying equipment for moisture removal upon delivery are also eliminated while production efficiency is streamlined, worker safety improved and consistent product quality assured.

Ideal for dry processing salt, potash, fertilizer, fly ash, alumina, manufactured sand, diatomaceous earth, and a diverse variety of minerals, aggregates and other materials in 24/7 operation, the classifier line comprises three different models using three different methods of classification, all custom designed and engineered based on the application to meet specific production goals and end product specifications. Operating entirely without moving parts for low maintenance, the gravitational classifier separates fines less than 150 mesh to 150 µm from more coarse material, the gravitational-inertial classifier separates fines from 300 µm to 36 µm, and the centrifugal classifier separates fines from 100 µm to 15 µm. The classifiers may be used in series to split feed multiple products at different cut points and often include a cyclone or bag house dust collector to meet air pollution control requirements.
