The utility model relates to a dispersing device for dispersing fibers (1), which is provided with a housing (2). The housing (2) is internally provided with a first operating tool (3) and a second operating tool (4), wherein, the operating tools (3,4) have shapes which are in rotational symmetry and coaxially configured and respectively provided with a plurality of teeth (6) that are configured in annular rows (5) that is concentric with the center of the operating tool. The tooth grooves through which the fibers (1) radially flow are provided among the teeth (6). Annular gaps exist among the tooth rows (5). The annular gaps are configured so that at least tooth row (5) of the operating tools (3,4) can extend into the annular gap of another complementary operating tool (4,3). Hereon, dispersion can be improved in a manner which is characterized in that: at least some teeth (6) of at least one operating tool (3,4) are provided with at least one groove (9) which extends in a radial direction; and the groove (9
