Typically used for blending powders, these mixers provide a high energy mixing action which can be used to thin down a thick mixture and mix it thoroughly. This type of mixer is usually used in the paint industry for dispersing pigment but they are also installed in several insecticides and liquid fertiliser plants to produce sprayed products that typically have suspended powders and solids.

Dispersers typically range from 37kw up to 200kw in size.
