PURPOSE:To produce granules having specified grain size with high yield by providing a cage-shaped stirring rotor arranged concentrically with a housing vessel and an impact rotor to the inside of the stirring rotor, in a cylindrical vessel, and repeating mixing, stirring, granulation, crushing, and classification. CONSTITUTION:A charging port 4 of raw material and a discharging port 6 are provided to a cylindrical vessel 1 having a horizontal axial line with one end closed with an end plate 2 and another end closed with a cover plate 3. Further, a cage-shaped stirring rotor 10 arranged concentrically with the body 1 is provided in the body 1, and an impact rotor 11 having an axial line held horizontally is provided to the inside of the rotor 10. Plural numbers of stirring element 14 inscribed to an internal cylindrical peripheral surface of the body 1 are provided protrudingly to the external periphery of the rotor 10, and plural numbers of impactor 18 and plural pins extending toward outside from the impactors 18, are provided to the external periphery of the rotor 11 protrudingly. The rotors 10, 11 are revolved with respectively necessary number of revolution. With this device, granules, particularly having 0.7-0.1mm. grain size are produced with high yield by repeating mixing, stirring, granulation, crushing, and classification.
