摘要:

益门煤矿选煤厂现有选煤工艺已不能满足实际生产的需要,必须进行工艺改造。针对益门煤矿选煤厂原煤细粒级含量大、需分别入洗不同煤种原煤和选煤厂规模小等特点,分析了工艺改造的难点,提出“一种工艺,两套系统”的设计思路,实现动力用煤与炼焦用煤的分选,并分析了改造后的分选效果及经济效益。

Abstract:

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
