Complete Compound Fertilizer Processing Line From Raw Material Crushing to Packaging

Product Description

Product Description

Compound Fertilizer Production Line

The Compound Fertilizer Production Line is a sophisticated, fully-integrated system engineered for the continuous and efficient manufacturing of high-analysis NPK fertilizers. Utilizing predominant industry technologies such as rotary drum granulation and slurry spraying granulation, this line precisely combines and processes raw materials including ammonium nitrate, urea, ammonium phosphates (MAP/DAP), and potassium chloride. These processes form uniform, nutrient-specific granules with homogenous nutrient distribution in each particle. The resulting product exhibits superior physical properties, ensuring excellent performance in storage, bulk handling, and precise mechanical application, thereby maximizing crop nutrient uptake and yield.

NPK Compound Fertilizer Production Line

This npk compound fertilizer production line is designed for versatility and high output, catering to the specific nutrient formula requirements of modern agriculture. It integrates batching, mixing, granulation, drying, cooling, screening, and coating into a seamless automated process. The system is highly adaptable, capable of producing a wide range of NPK grades (e.g., 15-15-15, 17-17-17) with consistent granule hardness, size, and nutrient content. It is the core solution for producing balanced, compound fertilizers that meet regional soil and crop needs.

FAQ

Frequently Asked Questions

Q1: What is the typical capacity of an NPK compound fertilizer production line?

A1: Capacity ranges from 30,000 to 300,000 tons per year depending on granulation method and plant layout.

 

Q2: What raw materials are used?

A2: Urea, Ammonium Nitrate, Ammonium Chloride, Ammonium Sulfate, Phosphate Fertilizers (MAP, DAP, SSP, TSP), and Potassium Salts such as MOP or SOP, proportioned according to the required NPK formula.

 

Q3: Which granulation method is better—rotary drum or slurry spraying?

A3: Rotary drum granulation is stable and suitable for large-scale NPK production, while slurry spraying provides higher uniformity and strength for high-quality granules; many modern plants combine both for best results.

 

Q4: Can the line produce multiple formulas?

A4: Yes, with automated batching and recipe control, the line can produce various NPK grades.

 

Q5: How is dust controlled during production?

A5: Cyclones, bag filters, and scrubbing systems ensure dust and gas emission compliance.

 

Q6: Are the granules suitable for blended fertilizer (BB)?

A6: Yes, uniform and hard NPK granules are ideal for BB fertilizer production.
