Abstract:
A dispersing apparatus comprising:a vessel having ports for supplying and discharging a material to be dispersed;first and second rotational shafts disposed in said vessel to run parallel to each other and rotatively;a plurality of stirring blades provided, in an axial direction and apart from one another at arbitrary intervals, for said first and second rotational shafts and located alternately in the axial direction; andparticle media arranged to perform a process for dispersing said material and enclosed in said vessel; wherein:portions of rotational regions of said stirring blades provided for said first and second rotational shafts overlap,said vessel has an inner surface formed by combining two circular arc-curved surfaces formed along outer rotational ends of said stirring blades provided for said first and second rotational shafts,said first and second rotational shafts are disposed horizontally,a vertical plane includes axes of said first and second rotational shafts, andassuming that radii of said first and second rotational shafts are rA and rB, rotational radii of each of said stirring blades provided for said first and second rotational shafts are RA and RB, and a distance between axes of said first and second rotational shafts is L, so that a relationship rB+RA=rA+RB<L.ltoreq.0.9 (RA+RB) is satisfied.
