50,000 tons Per Year NPK compound Fertilizer Production Line With
ISO
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. It can granulate NPK, NP, ANP, DAP, MAP,
CAN, SSP and other materials into compound fertilizer particles in
one processing line.
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
NPK Compound fertilizer production line usually includes 7
processes, batching, grinding, mixing, granulating, screening,
coating and packaging. Batching, mixing, granulating and screening
processes are necessary. Other processes are optional based on
different capacity.
It adopts the design solution of extrusion sliding model,the raw
materials pass through double roller,after that,enter into
scattering room, come out as granulation, a sieving was mounted at
the bottom of the machine, which is customized according to
client’s requirement, last, sieve out the granules which is
qualified, the rest of materials return to mixer and be
re-granulated.
