Ten Technological Processes of Compound Fertilizer Production Line

 

The compound fertilizer production process is the general process of compound fertilizer production. It is of great significance for users to invest and fully understand compound fertilizer production.

Below we will introduce each link of the compound fertilizer production process for you one by one:

The production process of compound fertilizer is raw material ingredient → mixing → crushing and agglomeration → granulation →grade screening → granule drying → granule cooling → secondary screening → finished granule coating → finished product quantitative packaging.

1. Ingredients of raw materials: raw materials are allocated in a certain proportion (mainly determined according to local market demand and local soil test results);

2. Mixing: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the overall fertilizer particles, and use a horizontal mixer or a pan mixer for mixing;

3. Agglomeration and pulverization: pulverize large agglomerates of materials that are evenly mixed and stirred to facilitate subsequent granulation processing, mainly using chain mills, etc.;

4. Material granulation: send the uniformly stirred and crushed material to the granulator through a belt conveyor for granulation (rotary drum granulator can be used, or double-roller extrusion granulator, disc granulator can be used. Granulator, etc.), this step is an indispensable and important link in the production process of compound fertilizer;

5.level screening: preliminary screening of semi-finished products, and unqualified particles are returned to the mixing and mixing link for reprocessing, generally using a drum screening machine;

6. Granule drying: send the granules made by the granulator and sieved to the dryer to dry the moisture contained in the granules.

7. Granule cooling: The temperature of the dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient for bagging, storage, and transportation, and it is cooled by a cooler;

8. Secondary classification of particles: the cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out, which can be screened by a secondary drum sieving machine;

9. Finished particle coating: coating qualified products to increase the brightness and roundness of the particles and make the appearance more beautiful. Generally, the coating machine is used for coating.

10. Quantitative packaging of finished pellets: The wrapped pellets are the finished pellets that are sent to the silo through a belt conveyor for temporary storage, and then connected to an electronic quantitative packaging scale, sewing machine and other automatic quantitative packaging and sealing bags, and stored in a ventilated place to achieve complete automation.

The ten links of the compound fertilizer production process are mainly connected by belt conveyors to ensure the fully automatic and stable operation of the entire compound fertilizer production line.
