Abstract
Continuous mixing apparatus provide rapid production of a mixture of high uniformity, low viscosity, low density, high stability after mixing, without an increase in amounts of subsequently supplied liquids. Continuous production of liquid or liquid containing mixtures consists of (i) continuously loading the apparatus casing with materials of different types which are flowable such as different liquids or a powder and a liquid, (ii) mixing the components between independently rotating upper and lower bladed disk turbine impellers to form a coarse mixture, and (iii) mixing the coarse mixture with an additional portion of a liquid being continuously supplied to the casing. The apparatus includes upper and lower bladed disk turbine impellers disposed in a mixing chamber within a casing. The impellers are capable of being rotated independently at different rotational speeds. A plurality of blades are attached to the impellers. Upper and lower ring shaped baffles extend from the inner wall of the casing. A material loading opening is provided in the upper part of the casing and a liquid supply pipe extends through a side wall of the casing. A discharge opening in the bottom of the mixi…
