Introduction of NPK Fertilizer Production Line
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
|

Advantages In NPK Compound Fertilizer Making Production Line
1, Productive Technology: this machine by the process of high
temperature drying, disinfection, decomposition and dried can make
fresh chicken which moisture is 65% becomes pure organic chicken
which moisture is below 13%.
2, Final Products: the organic fertilizer has many kinds of
necessary nutrients for the crops. After scientific research
departments detection: the fertilizer of nitrogen content is 2.6%,
the phosphorus content is 3.5%, potassium content is 2.5%, crude
protein content is 16-25%, organic matter content is 45%. is the
best choose fertilizer for planting pollution-free green food , can
also used for feeding the fish, cattle, pigs, etc.
3, Drum drying have high mechanization degree, bigger production
capacity, can run continuously.
4, Structure is good and simple, material through the resistance of
barrel, easy to operate.
5, Less malfunction, lower maintenance cost, low power consumption.
6, Widely used, uniformity is good of the products drying.
7, In the meantime of drying can also achieve the purpose of
sterilization and deodorization.
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.).
