煤炭洗选加工过程中有关粒度控制问题的探讨

近年来,随着矿井及选煤厂生产规模的不断扩大,洗选煤种以及生产方式的不断变化,在选煤设计及生产过程中关于煤炭的粒度控制出现了一些新的情况,有些甚至严重影响了选煤生产的正常运行。文章结合生产实际,阐述了煤炭粒度控制的必要性,并详细介绍了粒度控制的技术途径,为选煤厂设计及现场生产管理提供了有益参考。

Research on particle size control issues encountered in the process of coal separation and processing

In resent years,with the expansion of scale of production of coal mine and coal preparation plant,variation of coal type washed,and constantly changing of production mode,the new issues relate to the crushed particle size of coal encountered in the processes of design and production of coal preparation,some of the issues even serious influenced the normal operation of coal separation production.This paper accordance with production practice,detailed described the necessity of control of coal particle size and the technological approach of particle size,which provides the useful ideas for design of coal preparation and production management in site.
