【Introduction】:A slurry gravity thickener designed with tilted plate in sedimentation area
【Capacity】: 20～3500m2
【Improvement】: The stirring device is installed in the center of tiled plate thickener; the vibrator is installed on the outer wall of cone to accelerate the thickening and avoid blockage.
The vibrator reduces the blockage by high frequency vibration and impact.
Installing underflow valve to increase the concentration of underflow.
The tilted plates installed in thickener are good for large equipment and reducing the height which improve capacity by 2-3 times.
Firstly, mineral liquid is mixed uniformly and then carried into thickener. Secondly, by the action of cohesive and gravitational force, the majority of overflows are overflowed through the overflow groove. The minority of overflows form small cyclone inside the settling area and subsequently are compressed in the compressive area. As a result, granules are compressed by gravity and then fall down, while clear liquid moves upward. Finally, concentrations are discharged from the lower underflow tube.

In the thickening process of a graphite ore plant, considered to the cost, the client chose traditional transmission thickener firstly, but the thickening effect is not obvious, the slurry separation didn’t achieve the desired effect, which needs thickening again, so the client finally chose Xinhai tilted plate thickener. The thickening process of Xinhai tilted plate thickener is finished in the independent tilted plate channel, which shortens the overflow discharge path, improves the efficiency of classification thickening, solved the problem of the separation effect.
