The process flow of
compound fertilizer production line can usually be divided into: raw material ingredients, raw material mixing, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and final finished product packaging.
1, Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfide, ammonium phosphate (mono-ammonium phosphate, diammonium phosphate, heavy calcium, calcium), potassium chloride (potassium sulfate) and other raw materials are equipped in a certain proportion (according to market demand and soil test results).
2, Raw material mixing: the good raw materials will be mixed evenly to improve the overall uniform fertilizer efficiency content of fertilizer particles.
3, Raw material granulation: the mixed raw materials into the granulator granulation machine (can be used drum granulator, can also choose extruded granulator).
4, Particle drying: the fertilizer granulator made good particles into the
fertilizer dryer, the particles contained in the moisture drying, increase the strength of the particles, easy to save.
5, Particle cooling: the temperature of fertilizer particles after drying is too high, easy to caking, after cooling, easy to bag preservation, and transportation.
6, Particle grading: the cooled particles are graded, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
7. Finished film: The qualified product is coated to increase the brightness and roundness of the particles.
8. Finished product packaging: The coated particles, that is, the finished products, are bagged and stored in a ventilated place.
The above is the process flow of the
compound fertilizer production line. If you are interested in compound fertilizer production equipment, please contact Huaqiang Heavy Industry.
