The classifier receives the ultra fine particles and separates them according to particle size and specific gravity. The classifier overflow has a high percentage of water and fine solids that are pumped to a de-watering thickener. The underflow consisting of coarse particles returns to the repulper and is fed to the ball mill for further ...

Low dam spiral classifier. The overflow dam of the low dam spiral classifier is usually lower than the bearing center of the overflow end, so its settlement area is too small and the overflow production capacity is too low, while the agitation effect of the spiral on the pulp surface is too large. Therefore,the low dam spiral classifier is …

Shaking table separation, the main method in dealing with antimony oxide tailings, has too many defects such as poor operational stability and low recovery. A new technical idea was proposed to solve these problems by using an agitated Reflux Classifier to pre-concentrate the tailings before they went to shaking tables.
