郭二庄矿选煤厂历经多次技术改造和改扩建,工艺上存在一些问题影响生产及效益,需进行优化。一坑选煤厂主要工艺问题包含原煤无缓冲仓,跳汰中煤损失较多,两台跳汰机顶水共用;二坑选煤厂主要工艺问题包含一级筛为固定筛,筛分效率低,受煤坑堵塞,压滤机处理能力低等,通过针对性的分析问题,因地制宜提出解决方案,可有效确保选煤厂正常运行,提高企业的经济效益。

The coal preparation plant of Guo 'erzhuang Mine has undergone many technical transformation and expansion, and there are some problems in the process that affect the production and efficiency, which need to be optimized. The main process problems of Yikeng coal preparation plant include raw coal without buffer bin, coal loss in jig, and sharing of top water between two jig machines. The main process problems of Erkeng coal preparation plant include low screening efficiency of fixed screen, blocked by coal pit, and low processing capacity of filter press. Through targeted analysis of the problems and local conditions, solutions are proposed to effectively ensure the normal operation of coal preparation plant and improve the economic benefits of enterprises.
