1-3t/h small npk urea fertilizer processing plant manufacturer NPK granulating line

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 process.

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 plate.

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, etc.

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.

Production equipment:

1.Batching machine
For many kinds material weighting and send to next machine

2. Mixing machine
The mixed material should be mixed completely ,then get into granulator .

3. Granulation machine
Processing powder to granules.

4. Drying
After granulating, the moisture of fertilizer is bit high ,it’s not suitable for long-term storage so need drying process.

5. Cooling
The cooling machine is used to cool the hot fertilizer.

6. Screening
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 again.

7.Crusher machine
For bigger granules from screening machine.

8.Coating machine
For compound fertilizer coating

9.Packaging
Filling the bags, and sealing. After package ,the fertilizer can be sold .

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%.
