| Abstract: | Based on Fluent software, VOF and DPM models were applied to simulate the dispersion of light-floating particles in vibratory mixer and impeller agitator, and the factors affecting the dispersion effect of light-floating particles were investigated.The results show that the vibratory mixer has better pull-down effect and less power consumption than the impeller agitator under the same bottom clearance condition. |

| Keywords: | light-floating particle mixing flow field dispersion effect vibratory mixer impeller agitator numerical simulation |
