What is the fertilizer production process of compound fertilizer?

On the stage of modern agriculture, compound fertilizer has become the right-hand assistant of farmers with its efficient, convenient and comprehensive nutrition characteristics. The excellent quality of compound fertilizer is inseparable from the careful carving of advanced fertilizer production technology.

The production technology of compound fertilizer is a complicated and fine fertilizer production process. First of all, raw materials need to be selected and prepared. The raw materials of compound fertilizer mainly include nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and some compounds of trace elements. The quality and purity of these raw materials directly affect the quality of compound fertilizer. Therefore, when selecting raw materials, it must be screened in strict accordance with national standards and industry norms to ensure the quality and safety of raw materials.
Next, the raw materials are crushed and mixed. The various raw materials are crushed to achieve the appropriate particle size for better mixing. In the mixing process, advanced mixing equipment is needed to ensure that various raw materials can be evenly mixed together. The evenness of mixing is directly related to the fertilizer efficiency and stability of compound fertilizer.
Then, the granulation process. Granulation is the fertilizer production process raw materials into granules. Granular compound fertilizer has better fluidity, stability and convenience of application. There are many methods of granulation, such as disk granulation, drum granulation, extrusion granulation and so on. Different granulation methods have different characteristics and scope of application, which need to be selected according to the formula and production requirements of compound fertilizer.
After granulation is complete, it also needs to be dried and cooled. Drying can remove the moisture in the compound fertilizer particles and improve the strength and stability of the particles. Cooling
