摘要
在总结了跳汰选煤长期生产实践的基础上 ,引入了准重液的概念 ,提出了跳汰分选过程中按准重液密度分层的假说 ;准重液密度 =(矿粒重力 -流体对矿粒流动阻力 )
A concept of pseudo heavy liquid (PHL),based on summing up of long term jigging practice Introduced;and the hypothesis that jigging stratification according to density of PHL given,in which:Density of PHL=(particle weight fluid resistance against movement)÷particle volume
