Tailing screening can be used for sand washing in aggregate plant, slime recovery in coal preparation plant and dry discharge of tailings in concentrator. The tailing dewatering screen here is mainly used in the wet sand production line, and can be used together with sand washing machine or used alone.
The feeding tailings are evenly fed into the inlet of the screen by the feeding box (or cyclone). Firstly, about 1 / 3 of the water is removed at the place where the discharge screen plate is installed at a 45 degree angle with the horizontal direction. After entering the joint of the plane screen plate and the inclined screen plate, the material accumulates, and the material particles settle by gravity, forming a thin filter layer. The filter layer prevents the other particles from passing through the screen, making the filter layer thicken gradually.
The water that fails to pass through the screen forms a pool at the upper part of the filter layer. Because the filter layer is thin here, the water gradually drops off under strong movement. Due to the vibration state of high frequency and low amplitude, the tailings forming the filter layer vibrate more and more densely, and vibrates to the discharge port. The material forms a filter cake.
