Compound Fertilizer Production Line , NPK Fertilizer Production
Line
Introduction of NPK Fertilizer Production Line
First, according to a certain proportion of the preparation of raw
materials. For example: urea, ammonium nitrate, ammonium chloride,
ammonium sulfate, ammonium phosphate (phosphate ammonium,
diammonium phosphate, calcium carbonate, calcium superphosphate),
potassium chloride (potassium sulfate)
Working Process Of NPK Compound Fertilizer Making Production Line
The raw material batching, mixer, granulation machine, drying
machine, cooling machine, screening machine, film machine, packing
machine.
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 Fertilizer Production Line
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. This
machine can produce various compound fertilizer with different
concentration and different types (including organic fertilizer,
inorganic fertilizer, biological fertilizer, magnetic fertilizer,
etc.).
