Air classifier advantages. The accuracy of mechanical centrifugal air classifiers makes them ideal for when the separation curve or cut point is too fine for screens (200 to 400 mesh or finer), when the capacity is too large for screens (up to 800 tonnes per hour) and when system flexibility is required to meet various product …
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 ...

Gravitational inertial air classifiers use a primary and a recirculating secondary airflow to separate fines from coarse particles. Because the airflows are not affected by wear, the grading remains consistent to an accuracy of microns. At the same time, particle moisture remains at an optimal level. Different fractions ranging from 300 μm to ...
In vortex classifiers the air is rotated by stationary vanes (or tangential pipes); in rotor classifiers this is done by rotating blades. The latter devices may have …
