Patent ID: 8020798

Claim:
A pulverizing apparatus comprising: a raw material supply port provided in one end side; a product discharge port provided in the other side; a raw material pulverizing chamber for pulverizing a raw material supplied from the raw material supply port so as to discharge from the product discharge port; a rotor arranged in an upstream side within the raw material pulverizing chamber and formed by at least one thin plate; a cylindrical space in which the rotor is accommodated; a classifying space arranged in a downstream side of the cylindrical space and having a cylindrical shape with an inner diameter set smaller than the cylindrical space; and the product discharge port arranged in a downstream side of the classifying space, wherein the pulverizing apparatus pulverizes by causing the raw materials to collide against each other, or causing the raw material to collide against an inner wall surface of the raw material pulverizing chamber, by a gas flow generated by a rotation of the rotor.
