Roller extrusion and granulation production line

【Capacity】5T/H
【Applications】Granulation of various raw materials such as compound fertilizers, medicines, chemicals, feeds, etc., with high granulation rate.
【Equipment】Organic fertilizer production line,  disc granulation production line, rotary drum granular production line, BB fertilizer production line, etc.

Product description:
The process flow of the compound fertilizer transfer 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 manufacturing of various raw materials such as compound fertilizers, medicines, chemicals, and feeds. 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.

Roller production line process:

  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.
