PARTICLE PULVERIZING APPARATUS AND PARTICLE PULVERIZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a particle pulverizing apparatus capable of efficiently pulverizing coarse particles, and a particle pulverizing method using it. SOLUTION: This particle pulverizing apparatus is provided with a conical rotor 13 having a grinding surface 15 for grinding particles, an inverted conical rotor receiver 21 having a grinding surface 16 in opposed relation to the grinding surface 15 of the rotor 13 to grind particles and a motor 11 for rotating the rotor 13 in order to grind and pulverize the particles fed in the gap between the opposed grinding surfaces 15 and 16 to uniformly disperse the particulates in a dispersing medium. The grinding surfaces 15 and 16 for moving particulates made fine by grinding downward and opposed to each other in order to perform grinding treatment corresponding to a size are provided in positional relation so as to narrow the interval between the grinding surfaces downward.
