1. The collected pig manure is mixed with auxiliary materials such as sawdust fungus residue in proportion. The amount of auxiliary materials added depends on the moisture content of pig manure, and the moisture content should be controlled at about 45%.

2. Put the mixed materials into the fermenter and start aerobic fermentation. The fermentation temperature is controlled at 60-70°C, and the dough turning machine turns over once every two days. The function of turning is to increase the oxygen content of the material, speed up the fermentation process, and adjust the temperature of the material. The turning machine can also crush and shift the raw materials to make the materials mix more evenly. 
3. After the fermentation is completed, it is necessary to use a pulverizer to crush the material, which is beneficial to the later granulation.
4. After the material is crushed, it can be granulated by a fertilizer granulator. Common organic fertilizer granulators include: npk fertilizer granulator, drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator.
