| Abstract: | Progress on stirred mixing of gas liquid particle three phase system was reviewed.The mixing characteristics such as power consumption,gas hold up and critical speed were summarized.These characteristics were influenced by structure factors (impeller type,baffle configuration and gas sparger),operational factors(rotational speed,gas rate and particle fraction) and property factors(particle diameter and density),etc. |

| Keywords: | gas liquid particle three phase system stir mixing critical rotational speed power consumption gas hold up |
