Abstract To solve the problem of silt separation for Yellow River′s water for agricultural drip irrigation,the dish silt separator is designed considering the major characteristics of silt in Yellow River.The key constructional parameters of separator are calculated.The experiment system to separate the silt of Yellow River is discussed.The effects on separation efficiency are qualitatively summarized and evaluated by the analysis of gradation efficiency on limpid liquid.The major factor and best parameter combination are analysed by making a primary orthogonal regression test.The regression equation is found out based on orthogonal regression test.The results showed that the separation efficiency of separator is related to rotation speed of drum closely and is less related to nozzles and the gap between two dishes of disc separator.
