ドミルなどの分散撹拌機における媒体分離装置。[Scope of Claim for Utility Model Registration] 1. A medium and a dispersion medium are mixed in a stirring tank 1, the medium is dispersed and stirred by a stirring blade 3, and the medium is separated from the stirred workpiece and dispersed. In a dispersion agitator configured to discharge a medium to the outside of the machine from a discharge port, an annular stator 4 is formed on the outlet wall 2 of the stirring tank 1 so that its outer inner surface is flush with the inner surface of the outlet wall 2, and an inner cylinder is formed on the outlet wall 2 of the stirring tank 1. The shaped part 41 is formed and attached so as to have an end surface that protrudes in the axial direction by at least the diameter of the medium such as beads, and the rotating shaft 6 equipped with the stirring blades 3 has an outer diameter of the stator inner cylindrical part 41. A sand mill characterized in that a rotor 5 having an outer diameter approximately equal to , is attached facing the end face of the stator inner cylindrical part 41 with a gap therebetween so as to allow the liquid flow of the medium to pass therethrough and prevent the passage of the medium. Media separation device in dispersion stirrer such as. 2 Stator inner cylindrical part 4 1 stirring tank outlet wall 2
The length l protruding from the inner surface is at least twice the length of the medium d such as beads [l≧2d], and the difference between the outer diameter D1 of the stator inner cylindrical portion 41 and the outer diameter D2 of the rotor 5 is Half or less of the medium diameter d [D 1 −D 2 ≦d/
2] The medium separation device in a dispersion agitator such as a sand mill according to claim 1.
