Powdered material is fed downwardly into the mixing chamber through a vertical feed pipe while liquid is fed into the chamber in the form of annular thin film descending along the inner wall surface of an inverted frusto-conical overflow structure arranged in a liquid tank in encircling relation to the powder feed pipe. Accommodated in the mixing chamber is an agitator disc having a large number of upwardly extending projections co-operable with stationary projections formed on the top wall of the chamber. An annular board is placed afloat on top of the liquid in the tank substantially coaxially with the tubular overflow structure to serve the purpose of preventing any adverse effect of surface disturbance upon the formation of thin liquid film. |
