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.
Air Classifiers are rugged by design but they do require a degree of maintenance to keep them running at their most efficient. They’re also known to be very difficult to clean yet proper cleaning is vital to the efficiency of the units. Some of the issues that can arise are: Primasonics Acoustic Cleaners are the most efficient way to combat Air Classifier issues.

Depending upon the air flow rate and separator speed adjustment, discreet particles are acted upon by either the center seeking drag force of the air that flows through the classifier or the center fleeing centrifugal forces created by the turning of the classifier wheel. Rejected particles fall by gravity and are pulled back under the shroud assembly to the spinning hammers for further impact.
