NPK Fertilizer Manufacturing Plant 10-12 Tons Per Hour Capacity
NPK Fertilizer Production Line, Compound Fertilizer Production Line
Introduction to Compound Fertilizer Production Line
- Compound Organic Fertilizer Making Machine is the key equipment in compound fertilizer industry
- Suitable for hot and cold granulation and high, medium and low concentrations of mass production of compound fertilizer
- The shell uses special rubber slab lining or acid-resistant stainless lining board for auto scar removal and de-tumor
- Features high balling strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, and easy operation
Production Line Description
- We provide single machines (crushers, mixers, dryers, coolers) or complete compound fertilizer pellets production lines
- Chemical compound fertilizer material consists of various chemical single fertilizers
- Production process includes organic raw material crushing, mixing, granulating, drying, cooling, and packing
Raw Materials
Compound fertilizer contains two or all three basic plant nutrients (Nitrogen, Phosphorus, Potassium) plus microelements (B, Mn, Cu, Zn, Mo). Raw materials can be powder or bulk:
| Nitrogen |
Phosphorus |
Potassium |
Calcium nitrate Urea |
Single superphosphate Rock phosphate |
Kainit Potassium chloride |
Ammonium bicarbonate Ammonium chloride |
Dicalcium phosphate |
Potassium sulphate |
Nitrate of soda Ammonium sulphate nitrate |
Triple superphosphate |
Potassium nitrate |
Ammonium sulphate Ammonium nitrate |

Production Flow Chart
Compound fertilizer production line typically includes 9 processes: batching, grinding, mixing, granulating, drying, cooling, screening, coating, and packaging. Batching, mixing, granulating, drying, and screening are essential processes, while others are optional based on capacity requirements.
