摘　　要：文章介绍了"重介质旋流器+TBS干扰床+旋流静态微泡浮选柱"三段式煤炭洗选工艺的优势,利用TBS干扰床,对滇东北四种代表性高硫煤煤样进行粗煤泥的脱硫试验研究,说明TBS干扰床分选粗煤泥脱硫(降灰)效果明显,并对煤样具有广泛的适应性。TBS分选滇东北高硫煤2-0.5mm粗煤泥,分选各种中高硫煤、高硫煤均能保证产率在50%以上时,而精煤硫分控制在1.3%以下。This paper analysed importance of taking ash and pyrite from coal in China;introduced working theory of Teeter Bed Separator and advantage of three phases separating technics;chose four kinds of representative high-pyrite having coal in northeast of YunNan province to do the study of taking ash and pyrite from thick coals by using Teeter Bed Separator;made conclusion that Teeter Bed Separator had predominance in taking ash and pyrite from thick coals,so was fitted to various coals.
