Study on Rational Operation and Control of Classifying Hydro-cyclone

To improve the underflow concentration of the classifying cyclone,the operators tend to increasing the feed pressure unreasonable. The relationship between feed-pressure and classifying / thickening was studied with the 250mm hydro-cyclones on industrial scale. It was shown that the optimal classification performance and enrichment performance are at different operating pressures. So in practice,both of the classification performance and enrichment performance should be taken into account to choose the rational feeding pressure to avoid deteriorating the classifying efficiency.
