The sheep manure organic fertilizer production line is a professional production line that converts sheep manure into high-quality organic fertilizer. Its process usually includes multiple steps such as raw material pretreatment, fermentation, drying, screening, batching, granulation, cooling, and packaging. Below is a detailed introduction to the main process and granulation flow of the sheep manure organic fertilizer production line:

1、 Raw material pretreatment
Collection and preliminary crushing: Collect fresh or dried sheep manure and crush it preliminarily for better mixing with other auxiliary materials.
Raw material mixing: Mix crushed sheep manure with a certain proportion of auxiliary materials (such as straw, rice husk, sawdust, etc.) and microbial agents to adjust the carbon nitrogen ratio and moisture content of the materials, which is beneficial for the subsequent fermentation process.
2、 Composting fermentation
Composting construction: Stacking the mixed materials into strips or blocks for high-temperature aerobic fermentation, during which microbial activity accelerates the decomposition of organic matter.
Flipping ventilation: Regularly use organic fertilizer turning machines for flipping, increase oxygen supply, maintain suitable temperature and humidity conditions, and promote fermentation process.
3、 Drying and screening
Material drying: After fermentation, the material needs to be dried to reduce moisture content, usually using a dryer or natural air drying method.
Screening and grading: The dried material is screened through a vibrating screen to separate large chunks or impurities that have not been completely decomposed, resulting in a uniform and consistent matrix.
4、 Ingredients and granulation
Formula adjustment: Add appropriate amounts of chemical fertilizers and other trace elements as needed to adjust the nutrient composition of the finished organic fertilizer.
Granulation molding: Use an organic fertilizer granulator to press the prepared powdered material into granules. Common granulation methods include extrusion granulation, disc granulation, and drum granulation. Among them, sheep manure organic fertilizer production lines often use disc granulators or drum granulators to produce granular fertilizers.
5、 Cooling and encapsulation
Cooling treatment: After granulation, fertilizer particles need to be cooled to prevent deformation or breakage due to excessive heat.
Coating treatment: Some production lines will add a coating process, which coats a thin film on the surface of fertilizer particles to enhance their water resistance and stability, while also delaying nutrient release rate.
6、 Finished product testing and packaging
Finished product testing: Conduct physical and chemical index testing on the final product, such as pH value, organic matter content, total nutrients, etc., to ensure that the product quality meets the standards.
Finished product packaging: Use a packaging machine to bag, label, and prepare qualified products for sale.
The above is the basic process flow of the sheep manure organic fertilizer production line. It is worth noting that the specific operation of each step may vary depending on different production processes and equipment, so appropriate adjustments should be made according to the specific situation in actual operation.
