A cylindrical sieve screen is placed inside the machine body.

Materials are conveyed to the system through a quantitative feeding device.

They are mixed with airflow, atomized and enter the screen cylinder.

Through the wind wheel blades inside the screen cylinder, the materials are subjected to both centrifugal force and cyclone propulsion force.

The materials are forced to spray through the screen and discharged from the fine material outlet.

Materials and foreign objects that cannot pass through the screen are discharged from the coarse material outlet along the wall of the screen cylinder.
