无压给料三产品重介质旋流器选煤工艺在淮北矿业集团的应用

The application of pressureless feed three products dense medium cyclone in Huaibei Mining Group

介绍无压给料三产品重介质旋流器在淮北矿业集团所属临涣、淮北、石台3座大型矿区型选煤厂的应用情况———工艺流程特点及分选指标。并对原来的跳汰—重介质旋流器工艺进行了分析,进一步说明原料煤全部用重介质旋流器分选的合理性。

The technical process and separation indices of the pressureless feed three products dense-medium cyclone and its application in coal preparation plants in Linhuan,Huaibei and Shitai coalmines are introduced in this paper.At the same time,the process of pre-existed technology of jig-dense medium cyclone is analyzed and the reason that feed coals should be separated by dense medium cyclone rationally is illuminated.
