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
