PROBLEM TO BE SOLVED: To provide a fine pulverizer for further finely and efficiently pulverizing a large quantity of crushed matter obtained by crushing raw materials or various wastes to be finer. SOLUTION: The fine pulverizer comprises a vertical casing having an upper end part, a lower end part, a cylindrical circumferential wall, a supply port for an object W to be treated in the lower end part, and a discharge port for finely crushed matter in the upper end part; a vertical rotary shaft journalled with the center of the inside of the casing by the upper end part and the lower end part through bearings in a rotatable manner; a main suction blade and an auxiliary suction blade attached to the vertical rotary shaft in the discharge port side and the supply port side, respectively; a large number of rotary crushing vertical blades attached to the circumferential faces of a plurality of rotary wheels arranged up and down in the middle part of the vertical rotary shaft; and fixed crushed blades installed in the inner face of the vertical casing adjacently and on the opposite to crushing blades attached to the vertical rotary shaft. The pulverizer can pulverize a large quantity of wastes to finely pulverized matter with 0.01-5 mm particle size. COPYRIGHT: (C)2003,JPO
