    (54) Liquid flow mixer


    (57) A mixer for two liquid flows comprises a generally cylindrical chamber (51) having one open end (52) pro­viding an axial flow outlet for the mixed liquids, and one or more radial inlets (80,81,82) for the liquid flows to be mixed. Within the chamber are one or more radially extending impeller plates (55,56,57) rotatable to cause thorough mixing of the liquids as they flow through the chamber. The impeller plates are preferably mounted on an axial drive shaft (54) and sweep substantially the whole volume of the chamber upon rotation of the shaft.
