New Gravitational Classifier is Equipped with Pneumatic Air Classifier System

Press Release Summary:

The Gravitational Classifier automatically separates soft, dry materials without breakage, fragmentation or fines generation. The device passes current of air through continuous curtain of falling materials and directs the particulates towards series of vanes. The unit’s pneumatic air classifier system separates dry particles at cut point between 2 mm and 150 μm without using water and is suitable for separating salt, potash, limestone, fertilizers and manufactured sand.

Process Equipment Manufacturer Unveils Gravitational Classifier

Van Tongeren System Classifies Coarse Particles Without Generating Fines

Lebanon, PA: Process equipment manufacturer Van Tongeren America, Lebanon, Pa. (, has unveiled a Gravitational Classifier (GC) that automatically separates soft, dry materials without the breakage, fragmentation or fines generation typical of screens and rotary classifiers. Designed to prevent particle attrition with no moving parts, the Gravitational Classifier passes a current of air through a continuous curtain of falling material, directing the particulates towards a series of vanes. Coarse particles drop into the discharge for collection while particles finer than the cut point exit the classifier with the airstream to a cyclone, baghouse dust collector or cartridge filter. 

Designed to boost efficiency in separating salt, potash, limestone, fertilizer, manufactured sand and other materials, the pneumatic air classifier system separates dry particles at any cut point between 2 mm and 150 μm without using any water. Customdesigned and manufactured for each installation, the Gravitational Classifier is proven to perform continuously in unattended, 24/7 operation with nearly zero maintenance required.
