The screens are mounted in a trough that slopes downward from the back to the front of the machine at a predetermined angle. the back and forth oscillation action agitates the grain as it flows onto the first screen where large foreign materials are separated and move to the front of the machine and discharged while the grain passing through onto the  second screen, flows to the discharge outlet while the fine impurities pass through the bottom of sieve separately and discharged out.

 Take out large impurities by vibration of screen sieveboat.

Take out small impurities, dust...by air from suction fan
