摘　　要：振动分选是一种极为重要的分选方法,在谷物分选、金属矿物分选上有着广泛的应用。采用离散元模拟方法,研究了相同直径、不同密度的金属矿石在组合摆振下的分层现象。通过研究,明确了振动和摆动的组合相较于包括水平方向直线和竖直方向直线的单独振动模式有着更好的分层分选效果,为组合摆振式金属分选装备的研究提供了理论基础。通过摆振式分选设备对金属矿石和杂质进行分选,取代工人手工分选,提高了分选效率并降低了生产成本。Vibration separation is an extremely important separation method,which is widely used in grain separation and metal mineral separation.In this paper,the discrete element simulation method is used to study the stratification phenomenon of metal ores with the same diameter and different densities under combined shimmy.Through the research,it is clear that the combination of vibration and swing has better hierarchical sorting effect than the single vibration mode including horizontal straight line and vertical straight line,which provides theoretical basis for the research of combined swing metal sorting equipment.Metal ores and impurities are sorted by swinging sorting equipment,which replaces manual sorting by workers,improves sorting efficiency and reduces production cost.
