Van Tongeren developed three models of air classifier in 1958, using knowledge of air flow gained through the earlier development of cyclones. The equipment is used to classify particles into different size ranges (as opposed to a cyclone, which is designed to collect particles of all sizes). The three models were the gravitational, the ...

The centrifugal air classifier is as follows: Where D 50 is the "cut size", k is a constant dependent on the flow pattern (determined experimentally). D o is the diameter of the separation zone, H is the height of the separation zone, m is fluid viscosity, Q is volumetric airflow rate, N is rotor rotational speed and r p is true particle ...

The performance of an air classifier is evaluated by drawing the "actual efficiency curve" or "Tromp curve" that explains what portion of the material in the feed subjects to the underflow or overflow streams at a given size fraction [7], [14].The x-axis of the curve denotes to particle size and the y-axis denotes to the probability for being …

Efficient, ecological and economical separation. 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. Highly accurate separation.

Below an average particle size of 100 microns, mechanical classification methods are difficult and the use of air classification is required. Modern air classifiers are designed for use in the fine particle separation range (i.e. sub-sieve) with particular attention given to the requirements for particle separations in the less than 15 micron ...
