The process flow of compound fertilizer production line can be generally includes: raw material ingredient, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, final product packaging.

PRODUCT ADVANTAGES 

1. The compound fertilizer production line has the advantages of less investment, quick effect and good economic benefit.

2. Complete equipment process layout is compact, scientific and reasonable, advanced technology. Energy saving, no waste discharge, stable operation, reliable operation and convenient maintenance.

3. Material adaptability is wide. It is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials.

4. The product has high granulation rate. It can produce various kinds of compound fertilizers, including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers and so on.

5. Especially the granulation of rare earth and ammonium bicarbonate series compound fertilizers has filled the gap in China and occupied the leading level in China.

Process of Compound Fertilizer Production Line

1. Ingredients of raw materials: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, general calcium), potassium chloride (potassium sulfate) and other raw materials are equipped in a certain proportion (according to market demand and soil test results in different places).

2. Material mixing: mixing the raw materials evenly to improve the uniform fertilizer efficiency of the whole fertilizer granule.

3. Material granulation: Feed the uniformly stirred material into the granulator for granulation (drum granulator or extrusion granulator can be used).

4. Particle drying: The granulator is fed into the dryer, and the moisture contained in the granule is dried to increase the strength of the granule and to facilitate its preservation.

5. Particle cooling: After drying, the temperature of fertilizer particles is too high and easy to agglomerate. After cooling, it is easy to store and transport in bags.

6. Particle Classification: After cooling, the particles are classified. The unqualified particles are crushed and re-granulated, and the qualified products are screened out.

7. Finished film: coat qualified products to increase the brightness and roundness of particles.

8. Packaging of finished products: Film-coated particles, i.e. finished products, are packed and stored in a ventilated place.
