The dewatering screen adopts dual motor self-synchronization technology, universal eccentric block, adjustable amplitude vibrator, which is mainly composed of screen box, shock absorber, support system and motor. The material is fed evenly into the screen inlet by the feed box (or hydrocyclone). Remove about 1/3 of the water at the pre-dewatering screen plate installation at a horizontal 45°. After entering the junction of the flat sieve plate and the oblique sieve plate, the material accumulates. Material particles settle by gravity and begin to form a thin filter layer. The filter layer also prevents other particles from passing through the screen, making the filter layer gradually thicken. Water that fails to pass through the screen forms a pool in the upper part of the filter layer. Because the filter layer here is thin, the water is gradually removed under intense movement. The vibration state of high-frequency amplitude makes the particles forming a filter layer such as tailings become denser and denser, vibrating to the discharge port.
