Impeller Types - Euromixers

Close clearance impellers, such as the anchor impeller, are used for very high viscosity fluids and provide laminar macroscale blending at low speed and shear. These impellers are typically the size of the tank itself with the impeller almost scraping along the tank wall, hence the name close clearance impellers. Applications include inks, paints and adhesives.

How Agitator Impeller Design Affects Shear and Flow

The addition of a second, low shear impeller provides the bulk flow necessary to achieve proper distribution throughout the tank with significantly lower power. Alternatively, the mixing of flocculant (polyelectrolyte) requires minimal shear to avoid breaking up the long-chain molecules, which help to produce the coagulation. Slow moving, low shear aerofoils are preferable (bear in mind the ...

Rotofoil Low Shear Mixing Impeller Admix

The Rotofoil is a low shear agitator designed for mixing miscible liquids and dissolving solids that are unlikely to agglomerate. It prevents sedimentation, heat input and floc circulation, and is ideal for viscosities up to 5,000 mPa*s. It has been used for years across various industries including food and beverage, pharmaceuticals, cosmetic, chemical/coatings and wastewater treatment.

Mixing Fundamentals - Mixing Fundamentals

Mixing impellers are designed to “pump” fluid through the impeller and produce “turbulence” - both of these effects are essential to mixing. They produce “fluid velocity” and “fluid shear” respectively. Fluid velocity produces movement throughout the mixing vessel, intermixing material in one part of the tank with another, prevents solids from settling out and produces flow ...
