<p>An apparatus for the preparation of colored materials in powder form for the manufacture of ceramic tiles, which comprises a mixer constituted by an upper cover (6) connected to the supply line (3) of the base material and by a mixing chamber (5); a vibrating frame (9) located between upper cover and mixing chamber; a perforated baffle fixed to the vibrating frame, the vibrating frame is connected with seal to the mixing chamber. The apparatus is provided with a system for the generation of an operating vacuum pressure in the upper cover and an injection system of the colorant at the base of the mixing chamber. The apparatus of the present invention produces a method for the preparation of colored materials in powder form for the manufacture of ceramic tiles, wherein the atomized and/or granulated ceramic material of uniform particle size, containing or not containing coloring substances, is fed uniformly into a chamber under vacuum pressure with respect to the mixing chamber connected to said chamber through a vibrated perforated baffle; coloring particles are injected at the base of a mixing chamber; the atomized and/or granulated ceramic material falls by gravity and is sprinkled inside the mixing chamber; and mixing in gaseous phase of the atomized and/or granulated ceramic material with the rising current of coloring particles.</p> |
