From the perspective of the global renewable clean energy pattern, the use of organic fertilizer after processing by organic fertilizer granulator has many benefits. At present, biomass, wind, hydro and solar energy are the most important sectors in the field of renewable energy. Compared with other energy sources, biomass energy with agricultural waste as the main raw material is less affected by the seasons, climate, weather and other environment, and has irreplaceable advantages. Organic fertilizer granulator is the latest scientific and technological product developed by Agricultural Machinery Research Institute after many years of fertilizer processing equipment design and production experience, and has obtained the national utility model patent. It is used for granulation of various organic matter after fermentation, breaking through the conventional organic fertilizer equipment granulation process, without drying and crushing raw materials before granulation, direct ingredients can be processed into spherical particles, which can save a lot of energy. The press roller of organic fertilizer granulator adopts inclined wheel. And the two ends are consistent with the inner and outer ring line speed of the die disk, there is no dislocation friction between the wheel and the die, which reduces the resistance, reduces the kinetic energy loss, and extends the service life of the die, which is a major difference with similar compression molding equipment. The roller is set evenly, the operation is stable, the service life is long, is the current organic fertilizer production line market more popular fertilizer granulation equipment.
