High-Speed Dispersers

High-Speed Dispersers

High-Speed Dispersers play an important role in processes where rotor-stator high shear mixers may not provide the most effective solution.

A common example of this is the incorporation of “difficult to wet” powders in liquid bases, that are prone to agglomeration.

The HSD mixer features a serrated tooth impeller. The high peripheral speed of the impeller causes centrifugal displacement of the base fluid, resulting in a powerful vortex. Powder is drawn down into the vortex and subjected to intense shear at the tip of the impeller blade, resulting in rapid dispersion.
