摘　　要：扇形溜槽与圆锥选矿机均属弱紊流流膜选矿设备,选矿原理相近,其结构简单,省水,省电,试验研究处理能力适中。从影响扇形溜槽选别效果的因素尖缩比、给矿浓度、槽底倾斜角、给矿量等进行分析,在改变截矿方式、槽底形状等方面进行优化。通过扇形溜槽组和圆锥选矿机对某选铁尾矿的试验研究表明,优化后的扇形溜槽和3DSD型圆锥选矿机的富集比和精矿回收率相近且均较理想,说明用扇形溜槽组在实验室的条件下,可以对圆锥选矿机生产条件参数进行试验研究,并为圆锥选矿机生产操作提供技术依据。Both of sector sluices and cone concentrators belong to the weak turbulent flow film machines with a similar principle.It has advantages of simple structure,less water,less electricity and moderate processing capability in the experimental study.The influence factors for separation are analyzed such as the ratio of discharge end to feed,the feed concentration,the inclined angle of the lauder,the feed quantity and so on,and some aspects in sector sluices are optimized by changing the method of cutting minerals and the shape of the inclined lauder.The experimental study on sector sluices and 3DSD cone concentrator for some tailing indicates that the enrichment ratio and concentrate recovery of the optimized sector sluices are ideal,which is similar to that of 3DSD cone concentrator.Then the sector sluices can be used to research the processing parameters of the cone concentrators in the laboratories,which provide a technological basis for the production of cone concentrators.
