Air classifier

Air classifiers separate and recover ultrafine, fine and coarse materials in mining, aggregates production, sand manufacturing and other industrial processes. Dry classifying is often more environmental and economical alternative to wet classifying as no water is used. Gravitational air classifiers With the use of air flow, gravity and sharp directional changes, the gravitational classifiers perform accurate separations of material from 1,700+ microns down to 150 microns. Coarse particles are conveyed by gravity through a valve at the bottom of the unit, and fine material is conveyed by air to a fabric filter. The gravitational air classifiers are effective without the use of water, supporting EPA water-usage regulations. Gravitational inertial air classifiers Gravitational inertial air classifiers utilize secondary air flow, along with gravity and sharp directional change, to make adjustable, accurate separations of material from 300 microns to 63 microns. With no moving parts and extensive use of ceramics in wear areas, the gravitational inertial air classifiers require limited parts replacement and virtually no maintenance. The gravitational inertial air classifiers are widely used to produce manufactured sand and mineral fillers. Centrifugal air classifiers Centrifugal air classifiers use secondary air flow to separate particles ranging from 100 microns to 20 microns. This air flow, as well as the diameter of the coarse-particles opening, is adjustable – for a clear, accurate cut point. Secondary air flow is also crucial in the removal of near-size particles.
