Abstract

ABSTRACT Feng Xuan (FX) dry separators can effectively separate coal-series kaolinite. Coal-series kaolinite from Inner Mongolia (China) was selected as the sample. Computational fluid dynamics (CFD) and the discrete element method (DEM) were used to study velocity field, pressure field, turbulent kinetic energy field, and particle-motion characteristics of the FX dry separator. The results showed that the air velocity and pressure of the four air chambers symmetrically distributed from the centre to the surrounding area, and their values gradually decreased. The heavy products were located at the lower part of the material layer and moved horizontally along the sieve plate, the light products were located on the upper part of the material layer and moved obliquely along the sieve plate, and the intermediate products aggregated along horizontal and inclined directions, and their compaction effect on heavy products was obvious at the end of the sieve plate. This study provided a new way to optimise the structural parameters of FX dry separators. GRAPHICAL ABSTRACT
煤系高岭土干选过程流场及颗粒运动特性分析
Feng Xuan (FX)干式分选机可有效分离煤系高岭石。选取中国内蒙古的煤系高岭石作为样品。采用计算流体力学(CFD)和离散元法(DEM)对FX干式分离器的速度场、压力场、湍流动能场和颗粒运动特性进行了研究。结果表明:4个气室的风速和压力由中心向周围对称分布,其数值逐渐减小;重产物位于料层下部沿筛板水平移动,轻产物位于料层上部沿筛板斜向移动,中间产物沿水平和倾斜方向聚集,在筛板末端对重产物的压实作用明显。该研究为优化FX干燥分离器的结构参数提供了一条新的途径。图形抽象
