Diagonal blade stirring rotors

also called cross-beam stirrer

The diagonal blade stirring rotor is mainly used for low viscosity fluids or suspensions. Typical for diagonal blade or cross blade stirrers are a minimum of four opposite stirrer blades arranged at a 45° angle. In contrast to propellers, the axial flow is complemented by a radial component that creates higher shear forces. Diagonal blade stirrers have a higher energy input than a propeller and a more turbulent flow.
It is used for homogenising liquids or suspensions of low to medium viscosity and is suitable for higher viscous fluids than a propeller in direct comparison.
