High Speed Dispersers
What is a High Speed Disperser?
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.

High-Speed Dispersers FAQ’s
In a word – Hugely!
Viscosity is a measure of a fluid’s resistance to flow. Measured in centipoises or Brix, it plays a key factor in determining which mixer types are appropriate, their diameters, speeds and the power required to drive them. Get in touch with our team who will be pleased to help.
