Abstract：In order to improve the cyclone separator collection performance indicators， such as separation efficiency and pressure loss， etc， the separation process and inlet separation theory of the high-efficiency low-resistance SLK cyclone separator was analyzed. The central investigation was focused on the effect of the inlet of SLK cyclone separator on separation efficiency and pressure loss. The test analysis results of prototyping SLK about fly ash presented the qualitative evidence for the function characteristics of this SLK cyclone separator. The results showed that the higher separation efficiency and lower pressure loss （100～400 Pa） compared to the same model separator was obtained.
