摘要
通过分析TBS精矿的粒度组成,发现影响精矿灰分的根本原因是高灰细泥物质含量较高,通过调整反冲水压力,更换分级旋流器底流口,对不同煤质原煤选用不同规格型号的筛孔等措施,以及对粗煤泥处理系统各环节的探索改造,降低精矿中高灰细泥物质的含量,提高了精矿产品的品位,实现了TBS精矿全部掺配到精煤产品,提高了精煤产率,使企业获得更高的经济效益。
Analysis of size composition of TBS concentration show,high-ash slime is the radical cause which influences the ash concentrate.Exploring reform of every links in coarse slime treatment chain was made,involving recoil water adjustment,changing underflow diameter of classification cyclone,choosing different types of screen aperture and the like.After the reform,high-ash is reduced,TBS concentrate grade clean coal recovery are improved,TBS concentrate are all mixed into clean coal production.All those contribute to the plant＇s economic benefit.
