Abstract (en)

[origin: EP0801974A1] The mixer for homogenising/dispersion liquids or pastes has a rotary mixer (4) at the base of the vessel. Material is driven by centrifugal action into the product chamber (10) from where it can recirculate to the vessel. A plate (15), concentric with a stator (7), which guides it, is notched at its circumference so that rotation opens, or closes, the recirculation passages (12). When passages (12) are closed the material is diverted to an external pump.
