Application scope of compound fertilizer production line;

The compound fertilizer production line has a wide adaptability and is suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, and feed. The product has a high granulation rate. Can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). Especially for the granulation of rare earth and ammonium bicarbonate series compound fertilizers, it fills the domestic gap and ranks at the leading level in China.

Production process of compound fertilizer:

1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, dicalcium phosphate, tricalcium sulfate), potassium chloride (potassium sulfate) and other raw materials are prepared in a certain proportion (based on market demand and soil testing results in various regions).
2. Raw material mixing: Mix the prepared raw materials evenly to increase the overall uniform fertilizer content of the fertilizer particles.
3. Raw material granulation: Send the mixed raw materials into a granulator for granulation (a rotary drum granulator or an extrusion granulator can be used).
4. Particle drying: Send the particles made by the granulator into the dryer to dry the moisture contained in the particles, increase their strength, and facilitate storage.
5. Particle cooling: The temperature of the dried fertilizer particles is too high, making them prone to clumping. After cooling, they are easy to store in bags and transport.
6. Particle grading: Classify the cooled particles, grind and re pelletize the unqualified particles, and sieve out the qualified products.
7. Finished film: Coating qualified products with film to increase the brightness and roundness of particles.
8. Finished product packaging: Pack the particles that have been coated with film, that is, the finished product, into bags and store them in a well ventilated area.
