Abstract

The presented article deals with the influence of one of the operating parameters of a screw separator during the enrichment of coal sludge. The author shows with her results how the process of enrichment of finely dispersed coal slurry proceeds along the cross-section of the working part of the apparatus, depending on its productivity with the same feed density and the cross-sectional width of the apparatus trough.

Keywords

Coal sludge, Enrichment of coal sludge, Operating parameters, Granulometric analysis, Screw separation.
