Gas-solid mixture enters the classification chamber.
Swirl flow generates centrifugal force → particles are separated by particle size.
Fine powder passes through classification wheel blades, discharged from the upper part and collected by filter bag / filter cartridge.
Coarse particles are thrown outward → discharged from the lower part.
Ultra-fine powder rises with airflow → enters fine powder outlet.
Cut point adjustable by rotating speed / air volume / negative pressure.
