N:P:K 15-15-15 NPK Fertilizer Granulation Production Line plant
The main equipment of N:P:K 15-15-15 NPK Fertilizer Granulation
Production Line plant as follows:
| No. | Main Equipment | Function |
| 1 | Batching and Weighing System | Weighing and distributing various raw materials according to
formula. |
| 2 | Chain Crusher | Crush raw materials cakes and big granules |
| 3 | Mixer machine | Mix powder evenly, If necessary, add water, or other
micro-elements. |
| 4 | Fertilizer Granulator | Make mixed powder into fertilizer granules |
| 5 | Drum Dryer Machine | Dry fertilizer granules to low moisture by hot air |
| 6 | Drum Cooler Machine | Cool fertilizer granules to normal temperature. |
| 7 | Screening Machine | Screen out the required size from fertilizer granules |
| 8 | Chain Crusher | Crush big granules to powder. |
| 9 | Coating Machine | Coating colour, anti-blocking agent, microelements etc on
fertilizer granules |
| 10 | Belt Conveyor | Belt Conveyor is a kind of machine to transfer the material
continuously. The belt works under the effect of the frictional
force. |
| 11 | Packaging Machine | Package fertilizer granules into bags |
Working Process of N:P:K 15-15-15 NPK Fertilizer Granulation
Production Line plant:
1. Raw materials and ingredients: urea, ammonium nitrate, ammonium
chloride, ammonium sulfide, ammonium phosphate (mono ammonium
phosphate, diammonium phosphate, calcium heavy, common calcium),
potassium chloride (potassium sulfate) and other raw materials are
prepared in a certain proportion (according to the market demand
and the results of soil testing in various places).
2. Raw material stirring: stir the prepared raw materials evenly to
improve the overall uniform fertilizer effect content of fertilizer
particles.
3. Granulation of raw materials: feed the mixed raw materials into
a granulator (drum granulator or extrusion granulator can be used).
4.particle drying: granulator granule into the dryer, the granule
containing moisture drying, increase the particle strength, easy to
preserve.
5.particle cooling: drying fertilizer particles temperature is too
high, easy to agglomerate, after cooling, easy to bag preservation,
and transportation.
6. Particle grading: the cooled particles are graded, and the
unqualified particles are crushed and re-granulated, and the
qualified products are screened out.
7. Finished film: coating qualified products to increase the
brightness and roundness of particles.
8. Packaging of finished products: put the coated particles, namely
the finished products, into bags in a ventilated place for
preservation.
Features of N:P:K 15-15-15 NPK Fertilizer Granulation Production
Line plant:
1. Compound fertilizer production line can production NPK
fertilizer, DAP and other materials into compound fertilizer
particles.
2. Compound fertilizer production line mainly used for producing
spherical particles with a diameter ranging from 1-10mm.
3. Raw material widely, the production formula easy to operate,
used to produce high, medium and, low grade of compound fertilizer.
4. Compound fertilizer production technology is mature, equipment
running stable and high efficiency
