Air Classifier Equipment for Precision Applications

Centrifugal force overcomes the drag force, causing larger, less aerodynamically particles to accelerate away from the rotor. A cyclonic chamber collects this coarse fraction and enables discharge through a rotary airlock fitted to the bottom of the machine. The balance between the drag force and the centrifugal force determines the cut-point.
