本文阐述了用重介旋流器分选粉煤时的3种流程—25～0mm不脱泥分选工艺;10～0.75mm:0.75～0mm分级选的分选工艺;2～0mm粉煤分选工艺。同时还介绍了分选前脱泥问题,磁铁矿回收问题,煤粉分选几种方法的比较等。
This paper describes the use of Dense Medium cyclone separation of pulverized coal when the three processes -25 ~ 0mm non-desilting separation process; 10 ~ 0.75mm: 0.75 ~ 0mm grading sorting process; 2 ~ 0mm pulverized coal Selection process. At the same time also introduced before the separation of mud, magnetite recovery problems, the comparison of several methods of coal sorting.
