益门煤矿选煤厂两煤种极细煤分选工艺改造设计

针对益门煤矿选煤厂有原工艺已不能满足生产的需要、原煤细粒级含量增大、需分别入洗不同煤种原煤的问题,设计了重介质分选工艺,具有一种工艺,两套系统的创新性设计,实现了动力用煤与炼焦用煤的分系统分选,取得了较好的分选效果及经济效益。

Introduction of Transformation Design for Two Ranks and Ultrafine Coal Separation Process of Sichuan Yimen Coal Mine CHPP

Existing separation process of Sichuan Yimen Coal Mine CHPP can’t meet the needs of actual production any more, the transformation must be carried out. The CHPP has these characteristics: lots of ultrafine coal in RAW and handling raw coals in different ranks. This article analyzed the difficulties of the transformation and put forward the idea of “One Separation Process, Two Preparation Systems”, which can realize the respectively preparation systems for thermal coal and coking coal. Finally, this article analyzed the separation effects and economic benefits after transformation
