Abstract

The apparatus for the dispersion of powders in a liquid that is distributed over the whole outer surface of the particles comprises a set of two parallel, toothed, discs connected by a set of spacers whose length is between one-fifth and one-twentieth of the disc diameters. The spacers (15) are made of flat plates of sufficient width so that the ends, bent at right angles, provide a sufficiently large surface to allow the spacers to be bolted to the discs and hence provide a variety of assemblies.
