Dry Roller Press Fertilizer Production Line
10mm Pellets Irregular Shape - Dry Roller Press NPK Fertilizer Production Line With Chemical Fertilizer
NPK Fertilizer Production Line Overview
Our roller press granulator is a key fertilizer equipment in NPK fertilizer production lines. This roller-type granulator is a newly designed fertilizer roller compaction granulation device developed through our research. Materials are granulated at room temperature with no drying process required, making it more energy-efficient and cost-effective. With characteristics of small investment, large profits, and quick results, the double roller compactor granulator delivers significant economic returns for investors. It can be used in NPK fertilizer production lines with high, medium, and low concentration levels.
Raw Materials for NPK Compound Fertilizer Production
Compound fertilizer contains two or all three of the basic plant nutrients—Nitrogen, Phosphorus, and Potassium—as well as microelements such as Boron, Manganese, Copper, Zinc, and Molybdenum. Raw materials can be in powder or bulk form, primarily including:
| Nitrogen |
Phosphorus |
Potassium |
| Calcium nitrate |
Single superphosphate |
Kainit |
| Urea |
Rock phosphate |
Potassium chloride |
| Ammonium bicarbonate |
Dicalcium phosphate |
Potassium sulphate |
| Ammonium chloride |
Triple superphosphate |
Potassium nitrate |
| Nitrate of soda |

Working Process of NPK Compound Fertilizer Production
The double roller fertilizer granulator machine represents extrusion granulator technology. Dry materials are compressed into hard, dense blocks under pressure during the extruding process. These block materials are then crushed, screened, and granulated in the subsequent granulating process. The extrusion functions to remove air between particles and bring particles close enough to create interaction forces. Particle hardness in roller compaction granulation is primarily formed through molecular attraction. Our double roller press machine enables continuous extruding granulation through positive displacement.
