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.

The Whirlwind® Mobile Air Classifier effectively removes excess fines from aggregate products bringing materials formerly considered waste materials into specification. The Mobile Air Classifier’s dry separation process eliminates the need for water typically used in washing plants, which is especially important in remote areas where water is not readily available.

The Side Draft Air Classifier is a versatile, energy-efficient system for consistent separation of particles in the 100 to 400 mesh range offering a compact design and durable wear-resistant materials. The Side Draft delivers consistent, high-quality product regardless of variations in feed material through user-friendly air flow and speed changes. The Side Draft is capable of processing both abrasive and non-abrasive materials with optional ceramic wear liners.

The SuperFine advantage is the high degree of accuracy in the separation of particles from 3 to 45 microns with very tight particle size distribution and throughputs up to 13,000 kgs per hour. Its compact design makes it ideal for retrofitting to existing applications and is capable of both abrasive and non-abrasive materials.
