The sifter holder is placed inside the machine. Bulk materials mixed with airflow and atomization passed the screw conveyor device, enter the sifter holder. The undersize materials are sprayed through the screen cloth and discharged from the outlet under the action of centrifugal force and the cyclone propelling power, which caused by the blade inside the net tube. The oversize material, which cannot cross the screen cloth, is discharged from the rough material outlet along the inside surface of the tube.

Centrifugal sifter separator is special for light and sticky material screening, such as mica powder, milk powder,etc.
