Tailing dewatering screen can ease the tailings harm

Along with the increase of beneficiation factories, the tailings are also growing sharply, which contain a large number of toxic and harmful substances. And it can leakage into underground by slurry to contaminated soil and nearby bodies of water.

To address this problem, LZZG produced GP series tailing dewatering screen. It is driven by two vibration generators, which makes the screen move to-and-fro on line to achieve the filtering purpose. With the vibration of screen, the concentrated tailings materials are continuously threw up and down on the screen, the materials are loosen and crashed to the sieve, the small size materials are filtered away from the sieve holes. Finally it reaches the aim of classifying, dehydrating and desliming. Then the drag waste water will be recycling to avoiding the toxic and harmful substances leakage into underground.

The Process of Tailings Dewatering Screen

According to different kinds of tail pulp, different concentration of particles, different silt content, to arrange reasonable dry process. Dry drainage process of tailings dewatering sieve generally has the following several ways:

1. Thickener + mud pump

Condition:medium and large mines, the tail slurry throughput will reduce about 70%

Feature:simple craft, the obvious effect

2. Thickener or desander + dewatering screen(water content <15%)

Condition:solid particles in the pulp >70um(200 mesh), and recycled water quality requirement is not high

Feature:simple craft, cheap

3. Desander +thickener + filter press(water content <20%)

Condition:large tailing, silt content<10%

Feature:large space occupation, favorable effect

4. Desander+dewatering screen+thickener+filter press(dry mineral water content <15%)

Condition:any

Feature:low silt content will choose disk filter, high silt content suit pressure filtration equipment
