Product introduction
The process flow of compound fertilizer double-roller granulation production line can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final finished product packaging.
Performance features
The roller granulation production line has low investment, quick results, good economic benefits, one-time molding and dry granulation. The complete set of equipment has a compact process layout, is scientific and reasonable, has advanced technology, saves energy, has no three wastes, is stable in operation, reliable in operation, convenient in maintenance, and has wide adaptability to raw materials. It is suitable for the manufacture of various raw materials such as compound fertilizers, medicines, chemicals, and feed. Granules, the product granulation rate is high. It can produce compound fertilizers of various concentrations and types (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.). Especially for the granulation of rare and ammonium bicarbonate series compound fertilizers.
How it works
1. Raw material ingredients
Urea, ammonium nitrate, ammonium oxide, ammonium sulfate, ammonium phosphate (beryllium phosphate, diphosphate, heavy calcium, ordinary calcium), potassium chloride (potassium sulfate) and other raw materials are equipped in a certain proportion.
2. Stirring of raw materials
Stir the prepared raw materials evenly to improve the uniform fertilizer content of the fertilizer particles as a whole.
3. Raw material granulation
Send the evenly stirred raw materials into the double-roller extrusion granulator for granulation.
4. Pellets drying
Send the granules made by the granulator into the dryer to dry the water contained in the granules to increase the strength of the granules and facilitate storage. (Special raw materials can also be used without drying, saving costs)
5. Particle cooling
The temperature of the dried fertilizer particles is too high and it is easy to agglomerate. After cooling, it is easy to bag, store and transport. (Special raw materials can also be used without drying, saving costs)
6. Particle classification
Classify the cooled particles, unqualified particles are crushed and re-granulated, and qualified products are screened out.
7. Finished product coating
Qualified products are coated to increase the brightness and roundness of the particles.
8. Finished product packaging
Bag the film-wrapped particles, that is, the finished product, and store them in a ventilated place.
