Start by composting the cow dung to decompose and stabilize the organic matter. Then making use of generated heat to kill substances in dairy manure. Mix the cow dung with other organic materials like straw, leaves, or crop residues to create a balanced carbon-to-nitrogen ratio and enhance the composting process. Create compost piles and using suitable compost turner to ensure proper aeration and moisture levels. Turn or mix the compost regularly to promote decomposition.
If the composted cow dung is not finely textured, you can grind it to obtain a more uniform particle size. Grinding helps in achieving consistent granule size during the cow dung granulation process.
There are several methods to granulate the cow dung compost into fertilizer granules:
Use a drum granulator or disc pan pellet agglomerator. The composted cow dung is placed in the drum or agglomerator, and as the equipment rotates, the material adheres together, forming granules.
Extrusion granulation involves forcing the composted cow dung through an flat die extruder. The pressure and mechanical action of the machine shape the compost into granules. Extrusion granulation can be done using a specialized extrusion granulator.
3. Stirring teeth:
Another method is to convert the cow dung compost into spherical granules by stirring teeth. The machine mainly makes use of high speed rotary mechanical agitation force and the resulting aerodynamic force to bind the compost particles together, forming the granules.

Drying and cooling
After granulation, the fertilizer granules need to be dried to remove excess moisture and cool down. This helps improve their storage stability. Use a drying machine or spread the granules in a well-ventilated area to allow for natural drying. Cool the granules before packaging.
Screening and grading
Once dried and cooled, screen the fertilizer granules to remove any oversized or undersized particles. This helps ensure uniform size and quality. Grading can be done using vibrating screens or sieves.
Package the final fertilizer granules in bags or containers suitable for storage and distribution. Label the packages with necessary information such as fertilizer type, nutrient content, and application instructions.
It’s worth noting that the specific equipment and techniques used for granulation can vary depending on the scale of production and the resources available.
