air classifier operation

Air classifier - Wikipedia

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air. Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravityand lifts the material to be sorted up into the air. Due to the dependence of air drag on ob

Air Classifiers - Sturtevant Inc.

Sturtevant air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size or density. All three Sturtevant air classifiers offer durable construction, as well as time- and energy-saving advantages.

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.

Jul 01, 2016  The cut size of the operation is mainly influenced by the wheel speed and the air flow rate of the classification process (Benzer et al., 2001, Yu et al., 2014). It is also reported that the feed fineness has effects on the performance of the air classifiers ( Altun and Benzer, 2014 ).

Air Separators Air Classifiers Williams Crusher

The air classifier cyclone sorts material by inserting the material into a chamber that has a column of rising air. Air drag on the material supplies an upward force and lifts the material into the air. Since the air drag is dependent on the material’s size and shape,
