Study On The Classifying And Separating Regularity Of Composite Slime Cyclone

Coal separation technologies and their characteristics are introduced, coal slime separation and recovery technologies and their advantadges and disadvantages are analysed in detail, and so composite slime cyclone is put forward on the basis of the classification principle of hydro-cyclone and the separation principle of hydro-medium cyclone, which own classification and separation performances. The classification principle of hydro-cyclone and the separation principle of hydro-medium cyclone are analysed detailedly, then the principle of composite slime cyclone is introduced. With the Fluent6.3, the flow field in composite slime cyclone is simulated, and the tangential、axial and radial velocities in different spaces are analysed in detail. According to the classification and separation principle of composite slime cyclone and the results of the simulation, the structure is designed exploringly and maded. The experimentation system is structured, with the coal example of Da tun plant, the classification and separation performance is studied experimentally and exploringly, the result is that the classification and separation is obvious, with the diameters odopted by the paper, but the efficiency of the classification and separation is low. Additionally, combining the de-sliming screen of posterior process to analyse, the classification and separation result is very good, and composite slime cyclone has a good utilization prospect.
