Four blade high efficiency impeller

(impeller, stirrer, rabbler, beater, propeller, mixing blade, paddle, mixing arm) The axial flow paddles have large onflow diffusivity and low shearing force. It economizes power 30 40% in the same mixing intensity, and its mass transfer coefficient advanced 20% inthe same power. It is used specially in processes of mass transerring, heat transfer, suspending and oxygen dissolving of biology ferment. Dimensions of Four-Blade PropellersDJ
