Reformation of coal blending system in Sihe coal preparation plant

针对寺河矿选煤厂配煤系统存在的问题,采用CQM在线煤质分析仪,并将原煤给煤机改造为变频胶带给煤机,形成了精确配煤系统,从而实现了煤炭产品的在线检测、实时指导生产和精确配煤,使装车质量得到了很大提高,装车不合格率由原来的34.71%降到15.53%,且减少了商品煤质量过剩情况的发生,实现了煤炭资源的合理利用,提高了企业的经济效益。

According to the problem existed in coal blending system in Sihe coal preparation plant,using the CQM on line coal quality meter,and make the raw feeder replaced with frequency conversion belt coal feeder,which consist of the clean coal blending system,realized the on line monitoring and inspecting the coal quality,real time direction the production and coal blending,greatly increased loading coal quality,the unqualified loading coal rate decreased from 34. 71% to 15. 53%,reduced the quality excess the standard,rational use of the coal resource,lifted the economic benefit of enterprise.
