Разделение полидисперсных сыпучих материалов по плотности и крупности при напорном гидротранспортировании

Abstract

On the basis of research of firm particle movement in vortical forcing flow of a liquid has been made an estimation of an opportunity of its lag on different distance from bottom of the pipeline. It has been established, that the lag of particles with size from 0,25 up to 3 mm has been possible only on distance from bottom of the pipeline, which hasn’t exceeded deffinite size, which is border of lag. It has created an opportunity of separation of these particles from a flow. The dependence of lag border on criterion Reynoldse, density and concentration of a material which is transported has been investigated
