Anchor stirring rotors

Widely used

The anchor design is a commonly used stirring rotor, yet its area of application is relatively specialised. It creates a tangential flow and high shear forces between vessel wall and stirring blades.

Characteristic for anchors are the two bars aligned parallel to the stirring shaft which are connected close to the container bottom by a crossbar.
The essential stirring task is to reduce high-viscous layers that adhere to the container wall in order to intensify the heat exchange.
