NPK Compound Fertilizer Production Line , NPK Production Line
Introduction For Compound Fertilizer Production Line
(1) a composite organic fertilizer is the key equipment maker
fertilizer industry.
(2) suitable for cold granulation of fertilizer and high mass
production in low concentrations.
(3) a machine housing with special rubber sheet lining or acid
stainless steel plate,broach replace traditional equipment,
automatically go to scar tumor
(4) High spheroidization strength, good appearance, corrosion
resistance, wear resistance, low energy consumption, long service
life, convenient operation and maintenance, etc.
Description For Compound Fertilizer Production Line
1, we provide stand-alone, such as material mill, material mixer,
fertilizer dryer, fertilizer cooling machines. We can also offer
the entire line of compound fertilizer pellet production line.
2, chemical fertilizer raw materials is a single variety of
chemical fertilizer.
3, an organic fertilizer pellet production line comprises a feed
grinding, mixing, granulating, drying, cooling, packaging.
Raw Material For Compound Fertilizer 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 |
Flow Chart For Compound Fertilizer Production Line
Compound fertilizer production line usually includes 9 processes,
batching, grinding, mixing, granulating, drying, cooling,
screening, coating and packaging. Batching, mixing, granulating,
drying, and screening processes are necessary. Other processes are
optional based on different capacity.
