目前选煤工业应用较多的SKT型跳汰机基本都为两段机体结构,在处理灰分较高、煤质较差的原煤时,分选效率约为70%,分选效果不理想。以SKT-12型跳汰机为例,探讨分析一种三段机体结构的跳汰机及结合相应工艺,既可提高精煤质量又能有效提高精煤回收率的优化措施。 At present, the SKT type jig with more application in the coal preparation industry are basically two body structures. When the coal with high ash content and poor coal quality is processed, the separation efficiency is about 70% and the sorting result is not satisfactory. Taking the model SKT-12 jig as an example, this paper discusses the optimization measures of jigging machine with three-stage structure and combining the corresponding technology to improve the quality of clean coal and increase the recovery rate of clean coal effectively.
