Introduce Each Link of the Compound Fertilizer Production Process in Detail for Everyone

 The production process of compound fertilizer is the general process of compound fertilizer production, which is of great significance for users to invest and fully understand compound fertilizer production. The production process of compound fertilizer is roughly as follows: raw material batching, mixing and stirring, agglomeration and crushing, material granulation, first screening, particle drying, particle cooling, particle secondary classification, finished particle coating, and quantitative packaging of finished particles.

Below we 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 → first screening → granule drying → granule cooling → second screening → finished granule coating → finished product quantitative packaging.

• Ingredients of raw materials: (mainly determined according to local market demand and local soil test results).
• 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 disc mixer for mixing.

• Agglomeration and pulverization: pulverize large agglomerates of materials that are evenly mixed and stirred to facilitate subsequent granulation processing, mainly using chain pulverizers.
• Material granulation: send the evenly stirred and crushed material to the granulation machine through a belt conveyor for granulation (rotary drum granulator equipment can be used, or a pair of roller extrusion granulator, pan granulator can be used,etc.), this step is an indispensable and important link in the production process of compound fertilizer.

• Screening: Preliminary screening of semi-finished products, unqualified particles are returned to the mixing and stirring link for further processing, generally using a drum screening machine.
• Granule drying: The granules made by the granulator and passed through the first level of screening are sent to the dryer, and the moisture contained in the granules is dried to increase the strength of the granules and facilitate storage. Generally, a tumble dryer is used. 

• 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.
• The second 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 two-stage drum sieving machine.

• 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.
• 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 electronic quantitative packaging, sewing machines and other automatic quantitative packaging and sealing bags, and stored in a ventilated place to achieve full 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.
