摘要
针对神华煤的难成浆性,以乌沙山神华煤作为研究对象,以定黏浓度作为评价指标,利用安阳双环添加剂厂的MC型添加剂对神华煤进行了阳泉煤、淮南B煤、阳城煤、俄罗斯B煤、神火煤和大会战煤等六种成浆性能好的煤与神华煤的配煤湿法制浆实验,利用malven激光粒度仪测定所制浆样的粒度,经过Rosin-Rammler粒度分析,表明浆样的粒度均符合水煤浆的粒度要求,并达到了较高的堆积效率.通过定黏浓度的测定,得到配煤的成浆浓度都较神华煤的成浆浓度有较大的提高,其中以淮南B煤配煤组合的成浆效果最好,定黏浓度为66.83%.
In this article, Wushashan Plant＇s Shenhua coal is taken as sample for blending coal＇s slurring experiment because of Shenhua coal＇s difficult slurring property. In slurring experiment, the MC additive of Anyang additive factory is taken as the additive, the concentration at （800± 50） mPa · s is the criterion for valuating the CWS. Five Chinese coal（Yangquan coal, Huainan B coal, Yangeheng coal, Shenhuo coal and Dahuizhan coal） and one Russian coal （Russia 13） are chosen as prominent slurrying coal, who blend with Shenhua coal to make CWS by wet way. The CWS＇s particle distribution is determined by Mastersizer 2000 and analyzed by Rosin-Rammler distribution equation, the analysis results show that the CWS＇s particle distribution reach high accumulation efficiency. The CWS＇s concentration of blending coal is higher than the CWS＇s concentration of the original coal, the highest concentration 66.83% is gotten by the blending coal with Huainan B coal.
