NPK compound fertilizer is a balanced nutrient formulation essential for modern agriculture. It combines nitrogen (N), phosphorus (P), and potassium (K) into one uniform fertilizer product. To boost efficiency, minimize loss, and improve handling, most NPK fertilizer is produced in granular form.

Gofine Machine offer complete NPK fertilizer production lines equipped with advanced round fertilizer granules making machines, including pan granulators, rotary drum granulators, and new type organic & compound fertilizer granulators.

What Is an NPK Fertilizer Granulation Line?

An NPK fertilizer production line integrates batching, mixing, granulating, drying, cooling, screening, and packing processes to transform raw powder materials into uniform, hard, round fertilizer granules suitable for commercial sale.

Suitable Raw Materials for NPK Fertilizer

Urea, ammonium sulfate, ammonium chloride (Nitrogen sources)

Monoammonium phosphate (MAP), diammonium phosphate (DAP), superphosphate (Phosphorus sources)

Potassium chloride, potassium sulfate (Potassium sources)

Fillers, binders, microelements, humic acid (Optional)

Recommended Granulation Machines for Round Fertilizer Pellets

• New Type NPK Fertilizer Granulator

Wet granulation, high rotation speed

Produces round or oval granules

Suitable for high-organic or complex NPK formulas

• Pan Granulator (Disc Granulator)

Ideal for small to medium-scale NPK plants

Adjustable disc angle for better balling

Granule size: 2–6 mm

• Rotary Drum Granulator

Perfect for large-scale continuous production

NPK Fertilizer Production Process

A full NPK fertilizer granulation process includes:

Batching – Accurate proportioning of N, P, K materials

Mixing – Using a horizontal or double shaft mixer

Granulating – Forming round granules with a granulator

Drying – Reducing moisture with a rotary dryer

Cooling – Lowering the temperature to avoid caking

Screening – Separating qualified granules

Coating (optional) – Anti-caking or slow-release treatment

Packing – Automatic bagging and sealing
