前言重介质分选法早为人们所知,在工业上应用于煤炭、金属矿物和非金属矿物的处理上,已有多年。重介质静力分选机有鼓式、轮式和锥形式;重介质动力分选机有一般旋流器式、涡流旋流器式、多段涡流旋流器式和沃赛尔式。这些重介质分选设备所能达到的分选结果,已接近实验室重液分选的结 INTRODUCTION Heavy medium sorting has long been known for many years in the industrial application to the treatment of coal, metallic minerals and non-metallic minerals. Heavy medium static separator with drum, wheeled and cone form; heavy media power separator have a general cyclone type, eddy cyclone type, multi-stage eddy cyclone type and Wo Saier type. These heavy medium sorting equipment can achieve the sorting results, has been close to laboratory heavy liquid sorting knot
