Studied the solid particles cyclone separation under structural parameters and operating parameters of different hydrocyclone, the results showed that major factor influence split ratio is in the ratio of entrance to exit pressure of hydrocyclone. Exit pressure has a certain influence on the split ratio, the various of the diameter and cone angle of hydrocyclone (in the ratio of entrance to exit pressure is constant) have no influence on split ratio; With diameter and cone angle increase, the separation granularity gradually increasing and recovery ratio decreasing; With entrance pressure increase, the separation granularity of hydrocyclone decrease, the split ratio of underset will increase slowly; With the diameter of overflow pipe increase, the separation granularity of hydrocyclone increasing and recovery ratio decreasing; With the diameter of underset pipe increasing, the separation granularity of hydrocyclone decreasing and recovery ratio increasing.

在不同的水力旋流器结构参数和操作参数下，对固体颗粒的旋流分离进行了分析研究，结果表明：旋流器的排出口比是影响分流比的主要因素，进口压力对分流比有一定影响，水力旋流器的直径变化和锥段角度变化对分流比基本上没有影响；随着直径、锥段角度的增大，分离粒度逐渐增大，回收率降低；随着入口压力增大，水力旋流器的分离粒度变小，底流的分流比会缓慢增加；随着溢流管管径的增加，分离粒度增大，分流比明显减小，回收率降低；随着底流管直径的增加，分离粒度减小，分级效果明显下降，回收率会增加。
