Dry Roller Press NPK Fertilizer Production Line With Chemical Fertilizer
Introduction of NPK Fertilizer Production Line
Our roller press granulator is a key fertilizer equipment in npk fertilizer production line. Roller-type granulator is a new-designed fertilizer roller compaction granulation device developed & researched by ourselves. Materials are granulated at room temperature, and there is no drying process, more energy-saving and cost-reducing. With the characteristics of small investment, large profits, and quick results, the double roller compactor granulator will bring investors bigger economic returns. It can be used in npk fertilizer production line with high, medium and low concentration
Raw Material For NPK Compound Fertilizer Making Production Line
Compound fertilizer is the fertilizer containing two or all three of the three basic plant nutrients—Nitrogen, Phosphorus, and Potassium, as well as microelements, such as B, Mn, Cu, Zn, and Mo. The raw material can be powder or bulk, mostly are as below:
| Nitrogen | Phosphorus | Potassium | |
| Calcium nitrate | urea | Single superphosphate | Kainit |
| Ammonium bicarbonate | Ammonium chloride | Rock phosphate | Potassium chloride |
| Nitrate of soda | Ammonium sulphate nitrate | Dicalcium phosphate | Potassium sulphate |
| Ammonium sulphate | Ammonium nitrate | Triple superphosphate | Potassium nitrate |
Working Process Of NPK Compound Fertilizer Making Production Line
The double roller fertilizer granulator machine is the representative of extrusion granulator. Dry materials are compressed into hard & dense blocks at a pressure, which is the Extruding Process. Block materials are crushed, screened and granulated later, which is the Granulating Process. The functions of extrusion are to squeeze the air between particles out, and to make the distance between particles near enough to give rise to interaction forces. The particle hardness of roller compaction granulation granules is formed mainly due to attraction between the molecules. Our double roller press machine is continuous extruding granulation of positive-displacement.
Main Equipments Of NPK Compound Fertilizer Making Production Line
1. the dynamic or static batching machine
2. crushing machine
3. mixing machine
4. granulating machine
5. screen machine
6. packing machine
The instruction of the roller extrusion granulator
1. No drying technology, normal temperature granulating, once forming.
2. Low investment, quick profit, good economic returns, etc.
3. Combine granulating,forming,screening into one machine,making beautiful appearance
granules, easy operation and low energy consumption, etc.
4. Especially, DZJ-5. not only has the above features, but also upgrades its rack.The bearing
frame body is made of high quality and anticorrosive cast materials, so that it become more
stable and extends the roller’s service life.
Features of NPK Fertilizer Production Line
1, Simple machine structure
2, Easy operation and maintenance
3, Low power consumption
4, Once forming,no drying process,normal temperature granulating
5, Long service life
