PROBLEM TO BE SOLVED: To provide a superfine grain grinding system capable of taking in raw materials to be crushed and outside air from a supply nozzle side, while eliminating a high-pressure gas pipe or tube, and capable of forming the raw materials to be crushed into a superfine granulated shape at a time in a hollow part of a swirling crushing chamber, air current passage gutter, or the like, with air current from crushing nozzles and supply nozzles with filters. SOLUTION: The superfine grain grinder has a tank 27, the upper part of which has a cylindrical body casing 28. The body casing 28 has a top cover 28a on its upper side, a bottom ring 28b on its lower side, and intermediate multiple rings 28c having crushing nozzles with filters on its outer peripheral surface between them. The intermediate multilayered ring 28c is constituted by overlaying, e.g. first to fourth four intermediate rings 28c1 to 28c4. The set number of these intermediate rings 28c1 to 28c4 are determined by kinds of the materials to be crushed to be superfinely crushed by the superfine grain grinder. COPYRIGHT: (C)2009,JPO&INPIT
