重介质旋流器使用盐水代替传统的铁粉介质时,分选末煤的效果更好。文中介绍了直径250毫米的重介旋流器,使用铁粉作加重质处理1～0毫米煤的一些试验结果。以及用饱和盐水作为介质(比重为1.2的NaCl溶液)的一些很有意义的结果。重介质试验全部试验是在荷兰国营煤矿研究所进 Heavy medium hydrocyclone using salt water instead of the traditional iron powder medium, the final sorting coal effect is better. In this paper, we introduce some test results of heavy medium cyclone with a diameter of 250 mm and using iron powder as a weighting agent to treat 1 ~ 0 mm coal. And some interesting results with saturated brine as a medium (NaCl solution with a specific gravity of 1.2). Heavy media testing All tests were conducted at the Dutch State Institute of Coal Mine Research
