磁铁矿粉粒度对煤泥重介质旋流器分选效果影响的研究

摘要

This paper states the separating mechanism of coal slime separation by heavy meG dium cyclone.Separating results of coal slime separation by size fraction of magnetite power have been explored.The same particle size with different concentration of magnetite power have been selected in the separating experiment.The results showed that to achieve the best separating reG sult,the particle size is -0.045 mm and the concentration of magnetite power is 90%.%简述了煤泥重介质旋流器的分选机理，探索磁铁矿粉粒度对煤泥重介质旋流器分选效果的影响，试验选用了同种粒度不同含量的磁铁矿粉对煤泥重介质进行了分选试验研究，结果表明，选用粒度为-0.045 mm、含量在90％时的磁铁矿粉能够达到最好的分选效果.
