The main goal of a small-scale cow and sheep manure compound fertilizer production line is to convert cow and sheep manure into high-quality compound organic fertilizers. The process usually involves the following steps:
1. Collection and preprocessing
Collection: Regularly collect fresh or slightly stored feces from cattle and sheep breeding areas to avoid rainwater erosion and nutrient loss.
Pre treatment: Remove impurities (such as grass roots, plastics, stones, etc.) and adjust the moisture content to a suitable level, usually around 50% -60%.
2. Fermentation
Composting: Pre treated feces are piled up and fermented at high temperatures, naturally heating up to decompose harmful bacteria and insect eggs, while increasing organic matter and beneficial microbial activity. This process can be accelerated with the assistance of a turning machine.
3. Drying and sieving
Drying: After fermentation is complete, use a fertilizer dryer to further reduce the moisture content to 15% -20% for storage and granulation.
Screening: Use a vibrating screen to separate large chunks that have not been decomposed, ensuring uniform particle size and facilitating subsequent processing.
4. Adding auxiliary materials and mixing
Auxiliary material preparation: Prepare other organic materials (such as straw powder, peat soil) and inorganic fertilizers such as nitrogen, phosphorus, and potassium according to the formula.
Mixing: Use a fertilizer mixer to thoroughly mix the manure with the auxiliary materials, ensuring that each batch of fertilizer is evenly distributed.
5. Granulation
Choose an appropriate granulator, such as a roller granulator or a disc granulator, to make the mixed material into particles of the desired size. Roll granulator is suitable for relatively dry raw materials and can generate hard particles; The disc granulator is suitable for raw materials with slightly higher humidity.
6. Dry again
If necessary, the particles may be slightly heated again by a dryer to further solidify their form.
7. Packaging and Storage
Finally, use an automatic packaging machine to package fertilizer granules by weight and store them in a dry and ventilated area, waiting for sale or use.
matters needing attention
At every stage of the entire production line, strict adherence to hygiene standards is required to ensure the safety of finished fertilizers. In addition, appropriate investment in maintaining and monitoring the operational status of equipment can ensure the long-term stability and efficiency of the production line.
This small-scale cow and sheep manure compound fertilizer production line can not only effectively recycle livestock and poultry waste and convert it into valuable resources, but also help improve soil structure and promote crop growth. It is an important component of modern agricultural circular economy. Reasonable planning and implementation can not only protect the environment, but also bring considerable economic benefits to farms or enterprises.
