Npk Fertilizer Granulator: Analysis From Principle To Maintenance

 can mix the three main nutrients—nitrogen (N), phosphorus (P), and potassium (K)—accordingly and form them into granules for easy transportation, storage, and use.

The NPK fertilizer granulator machine uses a wet granulation process. The main process includes: raw material pretreatment, material mixing and stirring, granulation, drying and cooling of fertilizer granules, screening and packaging. The equipment uses a disc granulator or a double roller press granulator to form uniform granules with the help of a binder.

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.

Fertilizer granulation equipment is widely used in the production of various compound fertilizers, particularly high-concentration NPK compound fertilizers, slow-release fertilizers, and organic-inorganic compound fertilizers. The nitrogen, phosphorus, and potassium ratios can be adjusted to meet the needs of different crops to produce specialized fertilizers, such as rice fertilizer (20-10-10) and fruit tree fertilizer (15-15-15).

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.
