Introduction to the production process of organic fertilizer from poultry and livestock manure using disc granulation technology:

1. Transport the processed poultry manure directly to the raw material bin (or raw material mixer).

2. Transport livestock manure to the disc homogenizer and evenly add it to the rotating disc of the disc granulator; Drip liquid components or an appropriate amount of water onto the material in the disc through the liquid component distributor of the disc granulator to meet the required liquid phase for ball formation; The rotating disc and its edges generate frictional and centrifugal forces on the material, causing it to move in a circumferential direction and gradually aggregate into balls by rubbing and squeezing the powder particles together; Due to the difference in particle mass, the gravity and centrifugal effects generated are also different. When the gravity and centrifugal effects increase enough to overcome the friction between particles, they will be thrown out of the disk, and smaller particles will still remain in the disk and continue to aggregate fine powder particles.

3. Transport to the organic fertilizer dryer and exchange heat with the heat from the hot blast stove.

4. Transport the particles to the thermal screening for sorting, and the fine particles are directly returned to the disc homogenizer as the core to continue participating in the adhesion of particles into balls.

5. Transport to the organic fertilizer cooler and cool the fertilizer with natural or forced cold air.

6. Transported to the finished product screening machine, the large particles are crushed by the crusher and returned to the disc homogenizer for further granulation.

7. The qualified products after screening are transported to the coating machine for coating treatment.

8. Transport to the fully automatic packaging scale for weighing, packaging, and storage.

9. Drying, cooling, and workshop dust are discharged after passing through three levels of treatment including cyclone dust collector, labyrinth dust removal chamber, and wet scrubbing to meet the standard.

The production process of circular granulation of organic fertilizer from poultry and livestock manure is short, simple in structure, low in investment, and easy to operate, making it suitable for small and medium-sized enterprises.
