【摘要】 利用数值模拟的方法对结构创新型无压给料三产品重介质旋流器的流场进行了分析,并与传统三产品旋流器进行了对比,得出新型旋流器的浓缩效果和分选精度均比传统旋流器高的研究结论,因此更适于中煤或矸石含量高的难选煤及高密度非金属矿物的分选。更多还原

【Abstract】 This paper analyzed the flow field of new structure gravity feed three-product dense medium cyclone with method of numerical modeling,and compared with traditional three product cyclone.The result shows that the thickening effect and sharpness of separation of new type cyclone all better than that of traditional one,so that it well suitable for separating middling and difficult-to-wash coal with high refuse content as well as high density nonmetallic beneficiation.更多还原
