| Abstract: | The paper deals with principle governing operation of hindered bed separator.Based on comparison made among various methods for calculation of free settling velocity of coarse coal slime,the formula catering for calculation of free settling velocity of coarse coal slime has been derived.A lab hindered bed separator test system has been set up where a test has been carried out for separation of different size fraction of coarse coal slime from Wennan Colliery of Xinwin Mining Group,so as to explore general law governing coarse coal slime separation by hindered bed separator. |

| Keywords: | coarse coal slime hindered bed separator terminal velocity of hindered settling ecart probable |
