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
