What are the specific steps of NPK fertilizer production line?
The specific steps of NPK fertilizer production line are as follows: raw material batching → mixing → crushing and caking → granulation → primary screening → particle drying → particle cooling → secondary screening → particle coating of finished products → quantitative packaging of finished products. NPK fertilizer production line is equipped with mixer, fertilizer crusher, fertilizer granulator machine, screening machine, dryer, coating machine and electronic packaging scale.
Equipment flow of NPK fertilizer production line
1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, superphosphate), potassium chloride (potassium sulfate) and other raw materials are prepared according to a certain proportion (according to the market demand and soil test results in different regions).
2. Raw material mixing: mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency content of fertilizer particles.
3. Raw material granulation: the evenly stirred raw materials are sent to the fertilizer granulator machine for granulation (rotary drum granulator or extrusion granulator can be used).
4. Particle drying: the fertilizer granulator machine made particles into the dryer, drying the moisture contained in the particles, increasing the strength of the particles, easy to save.
5. Grain cooling: the temperature of the dried fertilizer particles is too high and easy to agglomerate. After cooling, it is easy to pack, store and transport.
6. Particle classification: the cooled particles are graded. In the npk manufacturing process, the unqualified particles are crushed and re granulated, and the qualified products are screened out.
7. Finished film: the qualified products are coated to increase the brightness and roundness of particles.
8. Packaging of finished products: bag the coated particles, that is, finished products, and keep them in a ventilated place.
