The raw materials for organic fertilizer can be methane residue, agricultural waste, livestock manure, and urban household waste. The investment of transforming waste into wealth is worth it; The entire production line can not only convert different organic wastes into organic fertilizers, but also bring environmental and economic benefits.

The working principle of organic fertilizer production line processing agricultural waste to produce fertilizers:
1. Directly enter the fermentation zone with recycled animal manure and other raw materials. After one fermentation and two aging piles, the odor of livestock and poultry manure is eliminated. At this stage, fermentation strains can be added to decompose the crude fibers in order to meet the particle size requirements for granulation production after crushing. During the fermentation process, the temperature of the raw materials should be strictly controlled to prevent excessive temperature from inhibiting the activity of microorganisms and enzymes. The stacker is widely used for flipping, mixing, and accelerating fermentation of stacks.
2. The fermentation materials that have completed the secondary aging and stacking process can be crushed. Customers can choose a semi wet material crusher, which has a wide range of adaptability to the moisture content of the raw materials.
3. Stirring: After the raw materials are crushed, other nutrients or auxiliary materials are added according to the formula for stirring. During the stirring process, a horizontal or vertical mixer is used to mix the raw materials and additives evenly.
4. Drying: Before granulation, if the moisture content of the raw material exceeds 25%, under certain humidity and particle size conditions, use a drum dryer for drying, and the moisture content should be less than 25%.
5. Granulation: Organic fertilizer granulator is used to granulate raw materials into balls, maintaining microbial activity. The survival rate of microorganisms using this granulator is over 90%.
6. Drying: After granulation, the moisture content of the particles is around 15% -20%, which generally exceeds the target. A drum dryer is needed for drying to facilitate the transportation and storage of fertilizers.
7. Cooling: The dried product enters the cooling machine through a belt conveyor. The drum cooler adopts air cooling products to fully eliminate waste heat and further reduce the moisture content of particles.
8. Screening: The drum screening machine achieves the classification of recycled materials and finished products. The recycled materials are returned to the crusher for further processing, and the finished products are transported to the fertilizer coating machine or directly to the automatic packaging machine.
9. Packaging: The finished product enters the packaging machine through a belt conveyor. The quantitative automatic packaging of finished products is carried out by this packaging machine, which has a wide quantitative range and high accuracy. When combined with a conveyor sewing machine with adjustable tabletop, it has high efficiency and is versatile. Meet the packaging requirements and usage environment of different products.
