PURPOSE:To enhance treating capacity by specifying the spreading angle of an acceleration pipe and also forming the collision face of a collision member into a hexagonal pyramid shape which has a specified angle for the direction of the acceleration pipe. CONSTITUTION:An acceleration pipe 2 is formed of a monotonic diffuser which has a spreading angle theta not smaller than 7 degrees and not larger than 9 degrees. A collision member 6 is formed into a pyramid shape whose collision face is regulated to an angle not smaller than 55 degrees and smaller than 90 degrees for the acceleration pipe. Thereby when resin and substance having tackiness are ground, melt sticking, a coagulated material and coarse particles are not caused. Therefore rise of dust concn. at a time of grinding is enabled and throughput of pulverization can be increased. |
