Abstract Based on the analysis of key structural and operating parameters which influence the separation efficiency of hydrocyclone,the orthogonal experiments are carried out with simulative experimental apparatus by the change of some parameters,such as underflow port diameter,inlet pressure,inlet material concentration and grain size distribution.The effects on separation efficiency were qualitatively summarized and evaluated by the analysis of gradation efficiency on suspending liquid at overflow port.The results show that the separation efficiency of hydrocyclone is related to the inlet grain size distribution. If the grain size distribution of suspending liquid at inlet is identical,the change of inlet pressure and underflow port diameter can influence the separation efficiency.
