Characterizing slurry hydrodynamic transport in a large
网页2011年8月10日A model is proposed to characterize the in-mill slurry hydrodynamic transport on the basis of experimental RTD data. It accounts for non-ideal flow conditions such as back-mixing, radial convective flow as well as bypass flows. Effects of both slurry % solids and ball load volume on slurry hydrodynamic transport and mixing were evident
