While supplying the raw material into the grinding chamber 2 through the air supply pipe 14
, high pressure air is injected into the grinding chamber 2 through the air supply chamber 15 and the air supply nozzle 16. The raw material supplied in this manner falls onto the rotating dispersion plate 7, moves to its outer periphery due to centrifugal force, and is dispersed towards its outer periphery at the upper part of the grinding chamber 2 by one dispersion blade 8. . The particles dispersed in this manner are sucked into the air jet ejected from the air supply nozzle 16, are accelerated, and swirl at high speed within the grinding chamber, whereupon the particles collide with each other and are ground. The particles thus pulverized are classified by a classification blade 9,
The finely divided product is carried by the airflow, passes between the classification blades 9, and is taken out from the discharge pipe 10, and the coarse particles are again blown toward the outer periphery by centrifugal force and are crushed again in the same manner as described above. Ru.

While the raw material was supplied to the grinding chamber 2 where the rotor 6 was rotating, a jet stream of high-pressure air was injected from the air supply nozzle 16, and the raw material was blown toward the outer periphery of the grinding chamber 2 by the dispersion plate 7. Furthermore, while rotating on the swirling flow of air, the products collide with each other and are pulverized, and the products, which are turned into fine particles by the classification blades 9, are taken out from the discharge port 4.

Even if there are coarse particles to be taken out, since the gap between them is a parallel inclined surface with a small gap, the upward component of the centrifugal force generated by the rotation of the lower end 12 of the classification blade 9 will remove the coarse particles. The particles are pushed upward along the inner circumferential surface of the base tube portion 11 and pushed back into the grinding chamber 2, and in this way, discharge of the coarse particles to the outside is effectively prevented.
