摘要
粗煤泥的高效分选是许多选煤厂实现精煤产率提高的关键,如何根据入选原煤特性合理选择粗煤泥分选工艺,已成为选煤设计中急需解决的问题。在对粗煤泥来源和特性分析的基础上,结合国内广泛应用的粗煤泥分选工艺,系统总结了基于煤泥重介质旋流器、螺旋分选机、TBS干扰床分选机、水介质旋流器的粗煤泥分选工艺的特点,并分析了各典型工艺在国内选煤厂的应用情况。
For a number of coal preparation plants,high- efficiency cleaning of coarse slime has become a key link for the increase of the yield of clean coal,and how to make rational selection of the cleaning processes according to properties of raw coal is a pressing matter and needs to be dealt with at once in coal preparation design work. Following an analysis of the source and characteristics of raw coal,and an overview of the coarse slime cleaning processes widely used in China,the paper presents a systematic summary of the distinctive features of the processes involving the use of heavy- media cyclone,spiral separator,teetered- bed separator（ TBS） and water- only cyclone,and an analysis of the performances of the above-cited typical processes in domestic coal cleaning plants.
