Helical ribbon impeller

for agitatorsaxial-flow

Chemineer provides an array of impellers for a variety of applications in the chemical and petrochemical, pharmaceutical, biotechnology, polymers and food and grain processing industries. If there were only one mixing job to do, only one impeller would be required. However, there is a very wide range of problems in agitation, and the best impeller for one application may not be the best impeller for another. The descriptions and discussions below are intended as a guide for impeller selection. Relative impeller sizes are compared to the P4 at equal horsepower and equal speed. Ideal for shear sensitive, uniform blending applications (polymers). A screw impeller produces effective high viscosity blending of shear sensitive polymers. This impeller provides good top-to-bottom turnover. Although blending is generally good, heat transfer is not as good as the close clearance high viscosity impellers. The screw impeller is suitable for fluids which are not too pseudoplastic with power law indexes less than 0.5.
