Cow dung is a high-quality raw material for organic fertilizer, rich in organic matter and nutrients like nitrogen, phosphorus, and potassium. Using a specialized organic fertilizer production line, it can be turned into efficient, eco-friendly organic fertilizer suitable for farming, soil improvement, and more.
Process Features
1.Fermentation
Fresh cow dung contains high moisture and microbes. It needs aerobic fermentation to kill pathogens, insect eggs, and weed seeds. Modern production lines often use track-type compost turners along with microbial agents to speed up decomposition and improve efficiency.
2.Crushing and Mixing
After fermentation, the manure is crushed using a half-wet material crusher to ensure even texture. During mixing, additives like straw, mushroom residue, or humic acid can be added to balance the carbon-to-nitrogen ratio and boost fertilizer effectiveness.
3.Granulation
Cow dung can be granulated using a disc or rotary drum granulator, depending on the product needs. Moisture is kept between 25%–35% to ensure high granulation rates and proper pellet strength.
4.Drying and Cooling
Wet pellets go through a drum dryer to remove excess moisture, then a cooler to prevent clumping.
5.Screening and Packaging
Finished pellets pass through a vibrating screen. Qualified products go to an automatic packer, while rejects return for re-granulation, ensuring consistent quality.
Benefits
1.Eco-friendly and efficient: Reduces pollution from cow manure and turns waste into resources.
2.Long-lasting fertilizer effect: Improves soil structure and increases crop yield.
3.High automation: Lowers labor costs and boosts productivity.
Using an organic fertilizer production line to process cow manure not only solves waste pollution from livestock farming but also produces high-quality organic fertilizer, supporting greener agriculture.
