摘　　要：针对传统液固流化床对难选粗煤泥分选效果差等问题,介绍了三产品液固流化床基本结构及分选过程,在不同床层压力和上升水速条件下对高矸难选粗煤泥进行了下室排矸效果的实验探究。In order to solve the problem of poor seperation effect for the diffcult washed coarse coal slime in the traditional liquid-solid fluidized bed. The basic structure and seperation process of threeproduct liquid-solid fluidized bed were introduced. Laboratory experiments were conducted in the lower chamber under different bed pressure and rising water velocity to explore the gangue discharged performance for high ash, diffcult seperated coarse coal slime.
