MODELLING THE MULTIPHASE FLOW IN DENSE MEDIUM CYCLONES Fine Coal Processing With Dense Medium Cyclones

Dense medium cyclone DMC units are widely used to upgrade run of mine coal in the coal preparation industry Their simple design belies the complex flow patterns that existing within each unit These are developed due to the size and density distributions of the feed presence of medium solids and the turbulent vortex that is formed The modelling of flow in a DMC is very challenging dense cyclones at a mine trivenischool dense medium cyclone coal wash plant circuit Each technology in use for the processing of fine coal therefore has its own place in
