PROBLEM TO BE SOLVED: To provide a method and a device for crushing, sizing and grinding in which an achievement rate of 60% or more is obtained even in a dry operation. SOLUTION: Materials to be treated are charged by rotation of a rotor 1 into between the rotor 1 and a fixed plate 2 facing the rotor 1 where at least a part of the fixed plate has a predetermined gap at the lower part of the rotor 1. The edges of the materials to be treated are eliminated by friction while the materials to be treated are made to buffer one another between the rotor 1 and the fixed plate. COPYRIGHT: (C)2003,JPO |
