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. |

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
