摘要：
为了严格控制洗煤成本，针对城郊选煤厂介耗偏高情况，通过优化粗煤泥处理工艺、实施低密度重介选煤、改善重介分选后续工艺与设备以及建立市场化考核体系等技术与管理措施，提高了介质的回收与净化效率，实现了介耗的大幅降低。该厂介耗最终稳定在0.3 kg/t原煤左右，并形成了一套全重介选煤厂超低介耗控制关键技术研究成果，达到了国际领先水平。

Abstract:
In order to strictly control the cost of coal washing, with considering the reasons of high medium consumption, Chengjiao coal preparation plant has performed a series of technology and management measures, optimizing treatment technology of coarse coal slime, completing low density dense medium coal preparation, improving the subsequent technology and equipment of dense medium system and establishing evaluation system. These technical measures completed the high efficient recovery and purification of medium, and reduced medium consumption sharply. Finally, the value of medium consumption is stable in approximate 0.3 kg/t relative to raw coal, and some key technologies of controlling medium consumption in a full dense medium coal preparation plant has been developed, with the advanced international level.
Key words: dense medium, coal preparation practice, medium consumption, ultralow medium consumption
