Application of CFD Technology to Teetered Bed Separator of Coarse Slime

CHEN You-liang,LIU Wen-li,ZHANG Lei,ZHANG Jin-ming,GAO Zheng,WEI Ge-lao(School of Chemical and Environment Engineering,China University of Mining and Technology(Beijing),Beijing 100083,China)  
The paper stated the application of the Computational Fluid Dynamics(CFD) technology to the development,research and structural optimization of the coal preparation equipment.With the applied cases,the paper introduced the application of the CFD technology to the research on the teetered bed separator of coarse slime.The results showed that with the simulation of the CFD technology,the flow field features of the four areas in the teetered bed separator of coarse slime would be different,the water flow velocity of the bed area would have several inflexion points,the velocity cross section of the separation area would be in parabola,the fluid distribution at the feeding area would be uneven and the water flow at the overflow area would be stable.Based on the above analysis,the improved distributor and the feeder structure could be applied to optimize the teetered bed separator of the coarse slime.
