ISO Standard Compound Fertilizer Production Plant - Ball Shape Granules Making
ISO Rotary Drum Granulator in Compound Fertilizer Production Line
Our ISO-certified rotary drum granulator is designed for efficient production of ball-shaped compound fertilizer granules with consistent quality and optimal performance.
Raw Materials for Compound Fertilizer Production
Compound fertilizer contains two or all three essential plant nutrients—Nitrogen, Phosphorus, and Potassium—along with microelements such as Boron, Manganese, Copper, Zinc, and Molybdenum. Raw materials can be in powder or bulk form.
| Nitrogen Sources |
Phosphorus Sources |
Potassium Sources |
Calcium nitrate Urea Ammonium bicarbonate Ammonium chloride Nitrate of soda Ammonium sulphate nitrate Ammonium sulphate Ammonium nitrate |
Single superphosphate Rock phosphate Dicalcium phosphate Triple superphosphate |
Kainit Potassium chloride Potassium sulphate Potassium nitrate |
Production Process Flow
The compound fertilizer production line typically includes 9 key processes. While batching, mixing, granulating, drying, and screening are essential, other processes can be customized based on production capacity requirements.
- Crusher Machine: Processes granular or lump materials into fine powder
- Batching Machine: Precisely weighs multiple materials and transfers them to subsequent equipment
- Mixing Machine: Ensures complete homogenization of materials before granulation
- Granulation Machine: Transforms powder mixtures into uniform granules
- Drying System: Reduces moisture content for optimal storage stability
- Cooling System: Returns fertilizer temperature to ambient levels
- Screening Machine: Separates non-uniform particles for reprocessing
- Crusher (Secondary): Processes oversized granules from screening
- Coating Machine: Applies protective coatings and additives
- Packaging System: Fills and seals bags for market distribution
