Features & Benefits

The Whirlwind® Air Classifier incorporates a self-contained fan and rejector blade classification system. Its internal fan design does not require cyclones, air locks or dedicated baghouse for product collection of particles in the range of 100 to 400 mesh. Offering a significantly smaller footprint than screening separation and much lower capital cost, the Whirlwind® is designed to process a wide variety of materials. Typical Whirlwind® applications include aggregates, animal proteins, crushed stone, ceramics, diatomaceous earth, flyash, food products, gypsum, metals, frac sand, silica sand, soda ash and more.

How it Works

Material is fed into the top of the Whirlwind® Air Classifier through the feed inlet and falls onto the rotating distributing plate. Centrifugal force sends the materials onto the lower distributing plate for even distribution into the airflow. Due to gravity, the larger particles settle into the coarse cone and finer particles are swept upward into the whirling selector blades for further classification. During the secondary separation, oversized particles are spun out of the air flow and drop down into the coarse cone. The selected fines continue through the circulating fan and into the fines cone. Fines drop out of the recirculated air flow by gravity at the fixed return air vanes.
