The finding provides a mixing device for dyeing powders, comprising a body (1) defining a closed volume provided with a hatch (4) for loading the dyeing powders, and a discharge pipe (6) provided with opening and closing means (7), said body being placed in rotation according to a substantially horizontal axis through motor means. Said body has plane surfaces defining a polyhedron, and the axis of rotation (X) is different from the axis of symmmetry and passes through two opposed vertices (2, 3) of said polyhedron. The mixing of the powders is carried out through successive detachments of the material, due to gravity, from the upper walls to the lower walls, with a violent impact. |
