Rotary Drum production line

【Applications】Hot and cold granulation and batch production of high, medium and low concentration compound fertilizers.
【Equipment】Organic fertilizer production line, compound fertilizer double-roller production line, disc granulation production line, BB fertilizer production line, etc.

The transfer granulator is one of the key equipments in the lime granulation, transfer granulator and crusher industry. It is suitable for hot and cold granulation and batch production of high, medium and low concentration compound fertilizers.

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 transfer granulator production line is an efficient and energy-saving production equipment, suitable for granulating various raw materials such as compound fertilizer, medicine, chemical industry, and feed. It uses advanced ply transfer granulation technology to evenly stir the prepared raw materials and then feed them into the granulator. Through the high-speed rotation and shearing force of the ply transfer, the raw materials form uniform particles inside the machine. This kind of production line has the characteristics of high degree of automation, high production efficiency, uniform product particle size, and good particle quality. At the same time, the transfer granulator production line also has the advantages of simple operation and convenient maintenance. Operators only need simple training and guidance to quickly master the operating skills and ensure the stable operation of the production line.

Working principle:
Compound fertilizer 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 uniformly stirred raw materials into the transfer 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.
  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.
  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.
