To increase the through put in the case of pulverizing a coarse powder into a const. objective particle size, by arranging disk fixed bodies having radial grooves formed on the plates at the front and back faces of a space, and disk rotors having radial grooves formed on the upper and bottom faces of a rotor in such a manner that the disk fixed body faces the disk rotator at a specified distance.
Disk staters 10, 12 (face plates) comprising face plates with radial grooves formed on one surface, and disk rotors 11, 13 (face plates) comprising face plates with grooves facing to the disk staters 10, 12 on the bottom part of the rotor 3 are attached inside a pulverizing machine. By forming the grooves in the inner part of the pulverizing machine, a coarse powder stock introduced from the space between the disk staters 10, 12 and the axis part of the rotor 3 generates gas flow motion by the rotation of both plates in the space between the face plates 10, 11 facing each other, which decides the pulverization capacity of the stock powders. Thereby, the stock collides to the slopes of the grooves formed on the face plates 10, 11 and is then pulverized. This process is repeated, and thereby, the coarse particles can finely be pulverized.
