  • HOW TO CHOOSE A MIXING IMPELLER – Mixer Direct

    2019-6-27 · Impellers are the component of the mixer which imparts flow. Their purpose is to transfer the energy driven by the motor to the contents of a tank as quickly and efficiently as possible. Each type of impeller can be categorized by its flow pattern, whether it's an axial pattern {parallel to the blade} or a radial pattern {perpendicular to the blade}.

    Typical flow patterns for an anchor impeller are shown schematically in Figure 8.20. In such systems, the flow pattern changes with the impeller speed and the average shear rate cannot be described adequately by a linear equation such as equation (8.9). Furthermore, any rotational motion induced within the tank will produce a secondary flow in the vertical direction; the liquid in contact with the tank bottom is .
