The process flow of the compound fertilizer production line can be divided into: raw material ingredients, raw material mixing, raw material granulation, particle drying, granular cooling, particle grading, finished packaging film and final product packaging.
Characteristics of Performance
The compound fertilizer production line has less investment, quick results and good economic benefits. The whole equipment process is compact, scientific and advanced. Energy saving and consumption reducing, no waste removal, stable operation, reliable running, convenient maintenance. The adaptability of raw materials is wide, and the machine is suitable for the granulation of compound fertilizer, medicine, chemical industry, feed, etc., and the granulation rate is high. This machine can produce various compound fertilizer with different concentration and different types. In particular, the granule for tombarthite and ammonium carbide compound fertilizer fills the domestic void and lead the country.
Working Principle
Process of compound fertilizer production line
Raw material ingredients: Urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, and coarse whiting, ca), potassium chloride, potassium sulfate and other raw materials are matched in proportion (according to the market demand and the around soil of test results).
Raw materials mixing: The mixture of the ingredients should be mixed to improve the uniform fertilizer efficiency of the granules.
Granulation of raw material: The raw material after mixing equably will be sent to granulator (drum granulator, and extruding granulator both can be used).
Granulation drying: put the granulation into the dryer, and the moisture in the granules will be dried, so that the granulation strength is increased and is easier to store.
Granulation cooling: After drying, the granulation’s temperature is too high and the granulation is easy to lump. While after cooling, it is easy to bagging to save and transport.
Particle classification: the cooling particles that have been cooled will be graded: the unqualified particles will be crushed and regranulated, and the qualified products will be sift out.
Finished film: The qualified products are coated to increase the brightness and roundness of granules.
Packaging of finished product: The particles that have been wrapped the film are stored in the ventilated place.
