Numerical Simulation of Multi-Impeller High Intensity Conditioning in Fine Coal Flotation

Abstract:

The numerical simulation of a mixing vessel with three layers of six 45° leaned blade disc turbine impeller was conducted by using the standard k-ε turbulence model and multiple reference frame method (MRF), the velocity field were analyzed. Results show that multi-impeller increases the fluid turbulence zone, strengthens the mixing effect and enhances the function of the axial velocity gradient of conditioning vessel.
