Inorganic fertilizers usually refer to fertilizers extracted from minerals or synthetic chemicals to provide plants with the necessary nutrients.
Common inorganic fertilizer raw materials include urea, ammonium nitrate, diammonium phosphate, ammonium sulfate, potassium nitrate, calcium nitrate, magnesium nitrate, diammonium phosphate, potassium phosphate, etc.
These raw materials can be produced into powdered inorganic fertilizers and granular inorganic fertilizer products through reasonable proportioning and processing.
Inorganic fertilizer production line process
Inorganic fertilizer production lines usually include raw material proportioning, crushing, mixing, granulation, screening, packaging and other links. Next, I will introduce you in detail their production process and supporting fertilizer equipment.
1. Raw material ratio
Inorganic fertilizer can be a single fertilizer or a compound fertilizer. For a variety of single inorganic fertilizer combinations, it is recommended to use an automatic batching system to achieve automatic and accurate weighing and batching.
In order to make the nutrients more uniform, the crushed raw materials are mixed and stirred with a mixer to ensure the uniform distribution of various nutrients and improve the uniformity and stability of the product.
The raw materials after stirring enter the granulator and are granulated according to the required particle size and shape to form formed particles.
The roller extrusion granulator is the best choice for efficiently obtaining inorganic fertilizer particles. It adopts a dry granulation process, and can obtain regular oblate inorganic fertilizer particles with one extrusion. The fertilizer particles after granulation do not need to be dried and cooled, and have the advantages of low energy consumption and high cost performance. It is a best-selling fertilizer granulation equipment.
Finally, the inorganic fertilizer particles that meet the requirements are packaged by packaging machines for easy transportation and storage.
The above is the process flow of a commonly used inorganic fertilizer production line. The fine operation and equipment selection of each step have an important impact on the quality and production efficiency of the finished fertilizer.
