选煤重介质悬浮液稳定性分析

通过对选煤重介质悬浮液各组分构成之间关系的理论推导,在分析固体体积浓度与煤泥含量关系的基础上,绘制不同密度下煤泥含量与固体体积浓度的关系曲线簇,指出同一密度下悬浮液中的煤泥含量可以有很大不同,且存在一个煤泥含量的最佳值,而煤泥含量在密度一定、固体物性质一定的情况下代表了悬浮液的黏度,而分选过程中悬浮液的稳定应包括密度的稳定和黏度的稳定,并对悬浮液密度稳定性试验方案进行研究和分析.

Analysis on stability of heavy medium suspension for coal preparation

With the theoretical deduction from the relationship between each component composition of heavy medium suspension for coal preparation,based on the analysis of the relationship between solid volume concentration and slime content,the paper drew the relationship curve cluster between the slime content and solid volume density under the different densities.The paper pointed out that the slime content in the suspension with a same density could be in big different and there would a optimized value of the slim...
