摘要
曙光选煤厂设立了粗煤泥独立分选环节,将现在的重介+浮选联合工艺改造成重介旋流器+粗煤泥分选+浮选联合工艺。改造后,粗煤泥一段分选底流灰分大于60%,二段侧溢流精煤灰分+0.25 mm小于11%,提高了分选效率,降低了介质消耗,提高入洗原煤处理量,经济效益显著。
The link of coarse coal slime independent separation is set up,the present technology that combines dense medium with flotation is transformed into that combines dense medium cyclone with coarse coal slime separation and flotation in Shuguang coal preparation plant.After transformation,coarse coal slime ash content of underflow is more than 60 percent in the first stage of separation,and clean coal ash content of side overflow is +0.25 mm less than 1 1 percent in the second stage of separation,it increases the separation efficiency,decreases the medium con-sumption,improves the handling capacity of washing raw coal,and obtains remarkable economic benefit.
