ABSTRACT:
A liquid-liquid mixer wherein each impeller is associated with one recirculation chamber or two such chambers, having substantially the same diameter as the impeller. Each such recirculation chamber has the effect of increasing significantly the number of dispersion-recoalescence cycles for a given residence time and in consequence it is possible to employ an impeller of a selectively large diameter -- 50-90% of the diameter of the vessel portion in which it is located -- and to operate at relatively low speeds of revolution.
