To downsize the whole of a granulator by pressing the crushed pieces into a press-in hole with sufficient press-in force.

There is provided a press-in forming mechanism 18 in which a periphery-forming part 18A pushing out the crushed pieces from a push-out hole 16a of a peripheral die 16, and a bottom forming part 18B pushing out the crushed pieces from a push-out hole 17a of a bottom die 17 at the lower part of a standing casing 11 by compressing the crushed pieces charged from a charging port 14 into the casing 11 using a screw 41 provided on a rotary drive shaft 25 to push in below, are disposed in vertical two stages. A bottom push-out roller 62 which is rotationally driven around a lateral axis in a radial direction and has a plurality of pressure teeth 62a on an outer periphery at the free end of a bottom pivot 61 installed to the rotary drive shaft 25, is provided to the bottom forming part 18B, and a peripheral push-out roller 53 which is rotationally driven around a vertical axis 52 and has a plurality of pressure teeth 53a on an outer periphery at the free end of a peripheral turning arm 51 installed to the rotary drive shaft 25, is provided to the periphery-forming part 18A.
