As a high-quality organic fertilizer source, cow manure is rich in various essential nutrients such as nitrogen, phosphorus, potassium, and abundant organic matter. After proper processing, it can be made into high-quality organic granular fertilizers. The following is the main equipment configuration for establishing a cow manure organic fertilizer production line to process granular fertilizers:

1. Raw material pretreatment equipment

Solid liquid separator: used for preliminary separation of solid and liquid parts in cow manure, reducing the water burden of subsequent processing.

Composting fermentation silo/turner: Through aerobic fermentation, organic matter is decomposed, pathogens are eliminated, stabilization treatment is carried out, and nutrient conversion rate is increased.

2. Crushing equipment

Organic fertilizer grinder: Crush fermented cow manure to the desired particle size, which is beneficial for subsequent mixing and granulation.

3. Hybrid equipment

Horizontal mixer: Mix the crushed cow manure evenly with other organic or inorganic raw materials, and add auxiliary materials such as straw powder, peat, humic acid, etc. if necessary.

4. Granulation equipment

Disc granulator: suitable for initial granulation, using centrifugal force and friction between materials to make the mixture into balls.

Squeezing granulator: For situations that require harder particles, the squeezing granulator uses strong compression to shape the material.

Drum granulator: Combining rotation and extrusion, suitable for large-scale production.

5. Drying equipment

Organic fertilizer drying machine: removes moisture added during the granulation process, prevents mold and clumping, and ensures particle hardness and stability.

6. Cooling equipment

Organic fertilizer cooling machine: helps particles quickly cool down, reduces thermal stress, and facilitates subsequent packaging and storage.

7. Screening equipment

Organic fertilizer vibrating screen: used to screen out qualified particles, remove particles that are too large or too small, and ensure consistent product specifications.

8. Wrapping equipment (optional)

Coating machine: Apply a protective film to the particles to enhance weather resistance and delay nutrient release.

9. Packaging equipment

Automatic quantitative packaging machine: Pack finished granular fertilizers according to predetermined weight for easy sales and transportation.

Design and configuration suggestions

When planning a cow manure organic fertilizer production line, appropriate equipment types and models should be selected based on factors such as raw material characteristics, target output, and market demand. In addition, reasonable layout, degree of automation, and environmental protection measures are also factors that cannot be ignored. The consultation and technical support from a professional team will greatly enhance the success rate of the project.
