【摘要】：为研究矿粒在螺旋溜槽分选流场中的运动轨迹,以BL600螺旋溜槽作为基础,利用FLUENT软件、离散相颗粒模型(DPM),建立了螺旋溜槽分选CFD模型,分析了分选效果与矿物颗粒比重及粒度的关系,阐明了螺旋溜槽分选流场中矿物颗粒运动轨迹规律。仿真结果与已有的螺旋溜槽在分选矿物颗粒运动轨迹研究相吻合,揭示了螺旋溜槽设备重选分选原理,证明了此CFD模型的可靠性,此模型的建立也为今后螺旋溜槽结构的改进优化提供了新的方法。
[Abstract]:In order to study the moving trajectory of ore particles in the flow field of spiral chute separation, the CFD model of spiral chute separation is established by using FLUENT software and discrete phase particle model. The relationship between the separation effect and the specific gravity and particle size of mineral particles is analyzed, and the movement trajectory of mineral particles in the separation flow field of spiral chute is clarified. The simulation results are in agreement with the existing research on the movement trajectory of the spiral chute in the separation of mineral particles. The principle of gravity separation of the spiral chute equipment is revealed, and the reliability of the CFD model is proved. The establishment of this model also provides a new method for the improvement and optimization of spiral chute structure in the future.
