Product Description

The dip angles of the gravity separator screen layer along the direction of length and width are called longitudinal dip and horizontal dip respectively. During separation, the screen layer can do reciprocating vibration under the function of drive system, and seed flows onto the screen surface. Under the function of the air flow of the fan, the seed on the surface can be separated, and the heavy seed shall fall below the materials, while, as the seed would move up along the vibration direction by the vibration of screen layer, the light seed shall float above the materials without contact with the screen surface, and the seed shall flow downward because of the horizontal dip of the screen layer. Besides, because of the function of the longitudinal dip, the seed shall move forward along the direction of length with the vibration of screen layer and finally be discharged by seed outlet. According to this, it can be known that because of the difference of the seed gravity, seed cleaning or separating can be realized by different seed moving paths on the screen surface.
