Experimental study of solid-liquid two-phase flow in a hydrocyclone

By using a new type of laser measuring instrument, a particle dynamics anal yser (PDA), radial and axial velocity components and the size of solid part icles in a hydrocyclone were measured, and the concentration distribution o f the solid particles was obtained. In analysing and discussing the separat ion mechanism of the solid particles, as well as the main causes of the lea kage of coarse particles to the overflow and the abrasion on the hydrocyclo ne wall, some new opinions are put forward.
