Abstract

An experimental study has performed to identify the mixing characteristics of basket mill by using PIV and LIF techniques. The velocity fields were measured at three sectors for each two types of basket mill model and various impeller speed. To verify the results of velocity field measurement and the concentration field, LIF measurement also was performed for three cases. There was an inactive region and a descending flow to the bottom of basket mill at the original model. But when the impeller type and the guide shape were changed, internal flow structure was improved suitably for mixing and dispersion. The improvement result in increment of inflow flow rate at the basket entrance about $10\%$.
