Potassium sulfate Fertilizer Production Line with Carbon Steel
5-6t/h
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.
Main Equipments Of NPK Compound Fertilizer Making Production Line
1. the dynamic or static batching machine
2. crushing machine
3. mixing machine
4. granulating machine
5. screen machine
6. packing machine
The instruction of the roller extrusion granulator
1. No drying technology, normal temperature granulating, once
forming.
2. Low investment, quick profit, good economic returns, etc.
3. Combine granulating,forming,screening into one machine,making
beautiful appearance
granules, easy operation and low energy consumption, etc.
4. Especially, DZJ-5. not only has the above features, but also
upgrades its rack.The bearing
frame body is made of high quality and anticorrosive cast
materials, so that it become more
stable and extends the roller’s service life.
Features of NPK Fertilizer Production Line
1, Simple machine structure
2, Easy operation and maintenance
3, Low power consumption
4, Once forming,no drying process,normal temperature granulating
5, Long service life
