  • the lid member 61 may be provided with a suction port 68 connected to a dust collector.
  • the fixed lid 66 is provided with three suction ports 68 .
  • the suction port 68 can communicate with the space inside the granulating section (see FIG. 11), and can collect dust generated in the granulating section by connecting a dust collector. As a result, scattering of dust during granulation can be suppressed, and deterioration of the working environment and problems can be improved.
  • the number of suction ports may be one and can be set as appropriate.
  • the granulating apparatus of the present invention can stably form pellets that do not easily lose their shape even from powdery or granular raw materials with a relatively high moisture content, so it can be applied to mass production processes for compost pellets, for example. In that case, it can be used in combination with existing waste composting technology, reducing the amount of waste incinerated.
