Abstract (en)
A dispersing and grinding apparatus which comprises a tank (6), a basket (9) disposed within the tank (6), containing a dispersing medium (8) and a stirring blade (7) disposed under the basket, wherein a material to be processed is made to flow within the tank, and the material to be processed entered in the basket (9) is dispersed by means of the dispersing medium (8). The basket (9) is formed into an annular groove shape constituted with a cylindrical inner wall (13) surrounding a stirring shaft (11), an outer wall (14) surrounding the inner wall (13) and a bottom wall (15) extending at the bottom portion of the inner wall and the outer wall. The dispersing medium is contained in the annular groove constituted with the inner wall and the outer wall. The stirring shaft (11) having a material-stirring blade (7) for stirring the material to be processed, extends through a cylindrical space formed at the center of the basket, and rotates under a free condition. Thus, the material-stirring shaft does not adversely affect the basket. The medium-stirring blade (10) for moving the dispersing medium (8) within the annular groove is disposed to the material-stirring shaft (11) or the medium-stirring shaft having the same core as the material-stirring shaft. <IMAGE>
