8-10T/H Fertilizer NPK 15-15-15 Compound Fertilizer Production Line
Introduction of NPK Fertilizer Production Line
NPK Compound fertilizer production line is widely applied to
produce compound fertilizer and the capacity ranges from
5000-200,000 tons/year. The process flow of the compound fertilizer
production line can be divided into: raw material ingredients, raw
material mixing, raw material granulation, particle drying,
granular cooling, particle grading, finished packaging film and
final product packaging.
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 |
Characteristics Of NPK Compound Fertilizer Making Production Line
The whole equipment process is compact, scientific and advanced.
Energy saving and consumption reducing, no waste removal, stable
operation, reliable running, convenient maintenance. The
adaptability of raw materials is wide, and the machine is suitable
for the granulation of compound fertilizer, medicine, chemical
industry, feed, etc., and the granulation rate is high.
The Process of NPK Fertilizer Production Line
1. Raw material ingredients: Urea, ammonium nitrate, ammonium
chloride, ammonium sulphate, ammonium phosphate (monoammonium
phosphate, diammonium phosphate, and coarse whiting, ca), potassium
chloride, potassium sulfate and other raw materials are matched in
proportion (according to the market demand and the around soil of
test results).
2. Raw materials mixing: The mixture of the ingredients should be
mixed to improve the uniform fertilizer efficiency of the granules.
3. Granulation of raw material: The raw material after mixing
equably will be sent to granulator (drum granulator, and extruding
granulator both can be used).
4. Granulation drying: put the granulation into the dryer, and the
moisture in the granules will be dried, so that the granulation
strength is increased and is easier to store.
5. Granulation cooling: After drying, the granulation’s temperature
is too high and the granulation is easy to lump. While after
cooling, it is easy to bagging to save and transport.
6. Particle classification: the cooling particles that have been
cooled will be graded: the unqualified particles will be crushed
and regranulated, and the qualified products will be sift out.
7. Finished film: The qualified products are coated to increase the
brightness and roundness of granules.
8. Packaging of finished product: The particles that have been
wrapped the film are stored in the ventilated place.
Working Principle of NPK Fertilizer Production Line
1. Granulation drying: put the granulation into the dryer, and the
moisture in the granules will be dried, so that the granulation
strength is increased and is easier to store.
2. Granulation cooling: After drying, the granulation’s temperature
is too high and the granulation is easy to lump. While after
cooling, it is easy to bagging to save and transport.
3. Particle classification: the cooling particles that have been
cooled will be graded: the unqualified particles will be crushed
and regranulated, and the qualified products will be sift out.
4. Raw material ingredients: Urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, and coarse whiting, ca), potassium chloride, potassium sulfate and other raw materials are matched in proportion (according to the market demand and the around soil of test results).
