Modern precision agriculture requires balanced nitrogen, phosphorus and potassium supply to boost crop yield and improve soil fertility. Granular NPK compound fertilizer features slow-release performance, high nutrient utilization and convenient storage, occupying the dominant position in the global agricultural fertilizer market. Traditional manual mixing and simple molding equipment cannot meet commercial standards, with low granulation rate, uneven particle size and unstable nutrient proportion. Our
NPK granulation line is a professional industrial compound fertilizer manufacturing system, adopting mature rotary drum granulation technology to realize standardized, high-efficiency and large-scale NPK fertilizer production for global fertilizer factories.
This full-set automatic NPK fertilizer granulation line covers complete production processes including raw material crushing, precise batching, uniform mixing, rotary drum granulation, drying, cooling, screening and finished product packaging. It is compatible with various fertilizer raw materials such as urea, ammonium phosphate, potassium chloride and medium trace elements. Through physical rolling and extrusion, powder materials are formed into round and smooth NPK fertilizer granules. The flexible formula adjustment supports the production of 15-15-15, 16-16-16 and crop-specific customized fertilizers, fully meeting diversified market demands.
Core Advantages of NPK Granulation Line
Mature Rotary Drum Granulation Technology Different from extrusion granulation equipment, this industrial NPK granulation plant adopts mainstream rotary drum granulation technology, which is more suitable for large-scale compound fertilizer production. The optimized drum structure enhances material bonding and rolling performance, ensuring smooth granulation process without material sticking or agglomeration. This mature technology guarantees stable operation and long service life, becoming the preferred solution for medium and large fertilizer manufacturers.
High Granulation Rate & Uniform Fertilizer Pellets The equipment achieves a granulation rate of over 95%, greatly reducing powder waste and improving finished product output. The produced NPK fertilizer pellets feature uniform size, high hardness, good water solubility and anti-caking performance. Stable particle quality avoids nutrient loss during transportation and storage, fully complying with international commercial fertilizer grade standards and improving product market competitiveness.
Stable Automatic Operation & Low Energy Consumption Equipped with PLC intelligent automatic control system, the whole line realizes precise batching and unmanned continuous production, saving labor costs effectively. The matched low-temperature drying and efficient cooling system reduces energy consumption while ensuring low moisture content of finished fertilizer. The fully sealed production design controls dust overflow, meeting international environmental protection standards. With sturdy structure and low failure rate, it greatly reduces long-term maintenance and operating costs.
Industrial Applications of Compound Fertilizer Granulation Plant
This versatile NPK granulation line is widely applied in professional fertilizer factories, agricultural technology companies and large-scale planting bases. It can produce general-purpose grain crop fertilizer, orchard special fertilizer, vegetable fertilizer and various medium-trace element compound fertilizers, supporting both capacity expansion upgrading and new factory investment.
