The NPK fertilizer granulator is the core equipment of the compound fertilizer production line. It uses advanced granulation technology to make uniform granules of nutrients such as nitrogen (N), phosphorus (P), and potassium (K) according to scientific proportions, greatly improving fertilizer utilization and application convenience.

Granulation Process

Raw Material Pretreatment

Nitrogen, phosphorus, potassium, and other raw materials are accurately weighed according to the formulated ratio and initially crushed and mixed in a fertilizer grinder.

Mixing

Add an appropriate amount of binder and water to the fertilizer mixer to achieve optimal granulation.

Rotary Granulation

The material is formed into uniform granules by centrifugal force in a disc granulator.

Drying and Cooling

The wet granules pass through a fertilizer dryer to remove excess moisture and then pass through a fertilizer cooler to cool and solidify.

Screening and Packaging

Qualified granules are screened and then packaged, while unqualified granules are returned for further granulation.

The NPK fertilizer granulator is suitable for producing compound fertilizers with various formulations, such as high-nitrogen compound fertilizers.

Core Advantages: This fertilizer equipment precisely controls the NPK ratio and adjusts granule roundness, achieving a granulation rate exceeding 80%. It also features low energy consumption and high efficiency, making it suitable for large-scale continuous production.

To ensure long-term, stable operation of the equipment, it is necessary to regularly check the lubrication of transmission components, clean the granulation disc, and replace worn dies and scrapers. The interior of the fertilizer equipment should be thoroughly cleaned after each downtime to prevent material caking and impacting subsequent production.

With the modernization of agriculture, nitrogen, phosphorus, and potassium fertilizer granulators are moving towards intelligent and energy-saving technologies, providing fertilizer granulation manufacturers with more efficient production solutions.
