Impeller is the key element of an agitator for an efficient mixing. As there are thousands types of impeller available for different applications, it means the selection of the suitable impeller is not easy, while at RIXU, we do it based on accurate calculation and more important, the “experience”.
Basically, there are two types of impellers, depending on the flow regime created:
Axial flow impellers impose essentially bulk motion, and are used on homogenization processes, in which increased fluid volumetric flow rate is important.
Radial flow impellers impose essentially shear stress to the fluid, and are used, for example, to mix immiscible liquids or in general when there is a deformable interface to break. Another application of radial flow impellers is the mixing of very viscous fluids.
