Helical ribbon and screw impeller

(impeller, stirrer, rabbler, beater, propeller, mixing blade, paddle, mixing arm) These low speed impellers operate in laminar region. Along the screwed plane, medium appears axial circulation flow. They are used in processes of mixing and heat transfer of middle, high viscosity medium. Outline of type LD is close to the inwall of tank and type LD has a large mixing diameter, result in the increase of liquid circulation inside the tank. It has applications in processes of heat transfer of high viscosity medium. Type LDG impeller combines the features of helical ribbon and screw impeller. Type ZLD and ZLG are suitable for taper-bottom tanks. Dimensions of Helical Ribbon and Screw Type ImpellersDJ
