摘　　要：介绍了高分选密度两产品旋流器的基本结构,分析了入料压力、悬浮液密度以及悬浮液煤泥含量对旋流器分选效果的影响,结果表明,压力过低或者过高都对分选效果产生负面影响,入料压力0.05MPa时分选效果最好;由于锥角增大,悬浮液的浓缩作用大大增强,悬浮液密度1.5g/cm3时可实现1.80g/cm3以上的高密度分选;煤泥含量为20%左右悬浮液稳定性较好,可达到较好的分选效果。The basic structure of high separation density cyclone was introduced, and the effect of feed pressure, suspension density and slurry content in the suspension on cyclone separation efficiency was analyzed. The results show that, inadequate and excessive feed pressure both affects the separation efficiency negatively and the best feed pressure is 0. 05MPa; the inspissation of suspension is greatly enhanced due to cone angle enlargement, and high density separation （above 1.80g/cm^3） could be realized with 1.5g/cm^3 suspension density; and the stability of suspension is better with 20% of coal slim achieving favorable separation efficiency.
