1-3t/h small npk urea fertilizer processing plant manufacturer NPK
Brief introduction of Compound fertilizer production line:
Compound fertilizer production line is widely applied to produce
compound fertilizer and the capacity ranges from5000-200000
tons/year. It can granulate NPK fertilizer, NP, ANP, DAP, MAP, CAN,
SSP and other materials into compound fertilizer particles in one
processing line. This equipment can specially used for
manufacturing compound fertilizers with different concentrations
and types, such as organic fertilizers, inorganic fertilizers,
biological fertilizers, and magnetic fertilizers, etc. It is mainly
used for producing spherical particles with a diameter ranging from
1mm to 3mm.
Advantages Compound Fertilizer Production:
1. Equipped with advanced fertilizer manufacturing technique, this
fertilizer production line can finish fertilizer granulation in one
2. Adopts advanced rotary drum granulator, granulating ratio is up
to 70%, high intensity of granules,
3. The inner cylinder body adopts high quality rubber plate lining
structure which prevents the raw material from sticking on the
4. Wide adaptability of raw materials, suitable for compound
fertilizer, pharmaceuticals, chemicals, fodder and so on.
5. High-quality, stable performance, anti-corrosion and
wear-resistant materials components, abrasion proof, low energy
consumption, long service lifespan, easy maintenance and operation,
6. High efficiency and economic returns, and the small part of
feeding back material can be granulated again.
7. Adjustable capacity according to customers’ requirements.
For many kinds material weighting and send to next machine
2. Mixing machine
The mixed material should be mixed completely ,then get into
3. Granulation machine
Processing powder to granules.
After granulating, the moisture of fertilizer is bit high ,it’s not
suitable for long-term storage so need drying process.
The cooling machine is used to cool the hot fertilizer.
There are some non-uniform particles ,after sieved screening
machine , the small particle diameter may be screened down for
twice processing. And bigger granules go to the crusher machine
For bigger granules from screening machine.
For compound fertilizer coating
Filling the bags, and sealing. After package ,the fertilizer can be
How to Produce the High Nitrogen Compound Fertilizer?
To produce high nitrogen compound fertilizer, one important
equipment is needed in the granulating process: the spraying
system. The melting tank melt the urea and then spray the melted
liquid into the granulating machine so that it will mix with powder
phosphate fertilizer, potash fertilizer and other nitrogen
fertilizer. Then with the help of the granulator, the liquid and
other raw materials will be mixed and granulated. This production
technology is used to produce compound fertilizer or complex
fertilizer with high nitrogen content from 25%-45%.
