动力用末煤的洗选从动力煤洗选工艺上考虑,最合理的方针是利用重介旋流器洗选部分筛余煤,以便降低所销售的全部筛余煤的灰分。用重介质分选机选动力块煤的选煤厂对所入选的块煤进行脱泥,同时筛出高水分的末煤。这样,通常就采用双层筛脱 Power for the end of the coal washing From thermal coal washing process considerations, the most reasonable approach is to use heavy-medium cyclone washing part of the sieved coal, in order to reduce the sale of all sieved coal ash.
