ABSTRACT:
A rotary mill for micronic grinding comprising an impelling mechanism for the solid materials to be ground, such as minerals and the like, consisting of a disc, the walls of which are perforated in such manner that the materials are discharged through the perforations, and flung against the peripheral wall of the mill, thus effecting the grinding. Both around the perforations in the disc and upon the peripheral wall a protective layer is formed of the material being ground, so that the grinding is effected by the impact of the material upon the material, thus forming a self-generated grinding process.
