Understanding the Process Basics
Transforming cow manure into a fine biofertilizer powder is one of the most efficient ways to recycle livestock waste and improve soil health. The cow manure bio fertilizer production process typically includes raw material collection, composting, crushing, screening, and packaging. Each step determines the nutrient balance and final powder quality. Whether you’re running a small organic farm or setting up a medium-scale fertilizer plant, understanding this process helps you plan investment and production layout more effectively.
1. Pre-Treatment and Fermentation
Fresh cow manure usually contains 75–85% moisture, which is too high for direct composting. The first step is solid-liquid separation, using machines such as a screw press separator or sloped screen separator to reduce moisture to around 60%.
Next, fermentation starts in piles or composting channels. Adding microbial inoculants accelerates decomposition and removes pathogens. During this stage, the temperature can rise above 60°C, ensuring sterilization. Most farmers use a crawler-type or groove compost turner to maintain oxygen and temperature balance during the 15–20 days of fermentation.
2. Crushing and Screening the Compost
Once composting is completed, the material becomes loose and partially granular. To produce a consistent powder, a semi-wet material crusher or vertical grinder is used to break down larger particles. Screening follows, where a rotary drum screener separates fine biofertilizer powder from coarse pieces. The screened coarse part can be sent back for re-crushing to minimize waste.
3. Optional Nutrient Adjustment and Mixing
Some producers enhance their organic manure powder production by adding trace minerals or nitrogen sources such as urea or humic acid. A horizontal mixer or ribbon blender ensures uniform blending, creating customized nutrient ratios depending on soil needs or local market demand.
4. Drying, Cooling, and Packaging
Although powder fertilizer generally requires less drying than granulated forms, moisture control remains essential for storage stability. A simple rotary dryer or air drying system can lower the final moisture to below 15%. Finally, packaging machines automatically fill and seal bags from 25 to 50 kg, preparing the fertilizer for storage or sale. Learn more!
Key Considerations for Investors
When designing a cow dung biofertilizer manufacturing line, customers often ask about cost, footprint, and automation. Typically, a small-scale powder fertilizer line (1–3 tons/hour) requires less space and fewer machines than a granulation line. However, maintaining consistent moisture and nutrient ratios is critical to ensure quality and avoid odor issues during storage.

Reliable equipment suppliers, such as YUSHUNXIN, can help configure layouts for different production scales, from farm-based operations to commercial processing plants, ensuring smooth and efficient bio fertilizer making from cow manure.
Conclusion
By following a structured cow manure bio fertilizer manufacturing process, producers can efficiently convert animal waste into nutrient-rich soil amendments. From fermentation to fine powder packaging, each machine plays a role in ensuring stability, quality, and long-term sustainability in organic farming.
