NPK Compound Fertilizer Production Line With Double Roller
Extrusion Machine
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.
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.
Raw Material For NPK Compound Fertilizer Making Production Line
Potassic fertilizers : potassium sulfate, potassium chloride,plant
ash etc.
Nitrogen fertilizers : ammonium chloride, ammonium sulfate,
ammonium sulphate etc.
Phosphate fertilizer : superphosphate, triple superphosphate,
calcium magnesium phosphate

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.
