Chicken manure is one of the most widely used raw materials in organic and biofertilizer production. Rich in nitrogen, phosphorus, and organic matter, it can be transformed into high-value biofertilizer granules through a well-designed fertilizer production line. For investors and fertilizer manufacturers, understanding the granulation process is the first step toward building a profitable chicken manure biofertilizer plant.
Step 1: Chicken Manure Composting and Fermentation
Fresh poultry manure contains pathogens, weed seeds, and excessive moisture. Therefore, aerobic composting is essential before granulation. Using equipment such as a groove type compost turner or windrow compost turner, chicken manure is regularly turned to improve oxygen supply and accelerate microbial activity.
This fermentation stage stabilizes nutrients, reduces odor, and creates the biological foundation for producing organic fertilizer pellets or bio-organic fertilizer granules.
Step 2: Crushing and Raw Material Preparation
After composting, the fermented chicken manure is crushed to achieve uniform particle size. Vertical crushers or chain crushers are commonly used in chicken manure fertilizer production lines. At this stage, functional additives such as beneficial microbes, humic acid, or mineral elements can be blended to improve fertilizer performance.
Uniform mixing ensures stable granulation and consistent nutrient distribution in the final biofertilizer pellets.
Step 3: Granulation of Chicken Manure Biofertilizer
Granulation is the core step in converting composted poultry manure into marketable fertilizer products. Popular granulation equipment includes:
- Disc granulators – suitable for medium-capacity organic fertilizer plants
- Drum granulators – ideal for continuous, high-output fertilizer granule production
- Roller compaction granulators – used when dry granulation is required
These machines shape powdered materials into round, uniform biofertilizer granules, improving storage, transportation, and application efficiency.
Step 4: Drying, Cooling, and Screening
Fresh fertilizer pellets usually contain excess moisture. A rotary dryer reduces moisture content, while a cooler stabilizes granule strength. Screening machines separate qualified granules from oversized or undersized particles, which can be returned to the granulation system.
This closed-loop design improves yield and reduces material waste in the chicken manure fertilizer granulation line.
Step 5: Coating and Packaging
To enhance granule durability and nutrient efficiency, a coating machine can apply protective layers or microbial agents. Finally, automatic bagging systems package the finished organic fertilizer granules for commercial distribution. Learn more!
Why Granulated Chicken Manure Fertilizer?
Compared with powdered fertilizer, granulated biofertilizer offers better flowability, controlled nutrient release, and higher market acceptance. With the right chicken manure biofertilizer production equipment, producers can turn agricultural waste into a profitable, sustainable fertilizer solution.
