Cyclonic Ultrafine Classifier

The Metso Cyclonic Ultrafine Classifier is a hybrid air cyclone that combines cyclone and classifier designs to separate very fine particles. 

This unit includes our unique inlet scroll which is designed with a smooth flow elbow to eliminate currents perpendicular to the main direction of gas flow that is present in standard conventional rectangular entrance cyclones. 

This creates a smooth and uniform flow in this unit which thus leads to higher efficiencies then conventional cyclones. 

In conventional air cyclones, the aim is to remove as much of the particulate from the airstream as possible. 

However the Cyclonic Ultrafine Classifier is designed to allow the finest particles to be removed in the ascending vortex. This separation is achieved by introducing a reverse airflow into the specially designed disengaging hopper that weakens the descending vortex and creates a stronger entraining force in the ascending vortex that draws the required particles away to the fines collector. 

Control of the separation point is achieved by varying the percentage of reverse airflow relative to the total air.
