Drum Granulator

rotary-drum-granulator

A drum granulator, also known as a rotary drum granulator, is a type of fertilizer granulation equipment that is used to produce granules from various materials, such as organic fertilizer, compound fertilizer, and bio-organic fertilizer.

Drum granulators are commonly used in the fertilizer industry, as they are effective in producing granules of consistent size and shape, which are easier to handle and transport compared to powders.

Application of Drum Granulator

Drum-granulator-application

Drum granulator can process a wide range of materials, including but not limited to:

  • Ammonium sulfate
  • Ammonium phosphate
  • Urea
  • NPK (Nitrogen, Phosphorus, and Potassium) fertilizers
  • Calcium superphosphate
  • Potassium chloride
  • Potassium sulfate
  • Diammonium phosphate
  • Triple superphosphate
  • Organic materials such as compost and manure.

In addition to fertilizers, drum granulators can also be used for processing other materials such as chemicals, pharmaceuticals, and food products. The selection of materials and the type of binder used can affect the quality, size, and shape of the resulting granules. It is important to select the appropriate materials and binder to achieve the desired properties of the final product.

Drum Granulator Structure​

Drum-granulator-structureThe drum granulator consists of several components that work together to produce the desired granules. The main components of a typical drum granulator include:

  1. Drum: A cylindrical steel drum that rotates on an axis and serves as the main body of the pelletizer.

  2. Drive assembly: A motor, gearbox, and coupling or belt drive system that powers the rotation of the drum.

  3. Lifting flights or fins: Internal fins or flights that help lift and tumble the material inside the drum, facilitating the pelletization process.

  4. Liquid spray system: A system that sprays a liquid binder or other additives onto the material inside the drum to form pellets.

  5. Feed chute: A chute through which the raw material is fed into the drum.

  6. Discharge chute: A chute that directs the finished pellets out of the drum and into a collection bin or conveyor.

  7. Bearings: Bearings that support the rotation of the drum.

  8. Seals: Seals that prevent material from leaking out of the drum.

  9. Frame: A frame that supports the drum, motor, gearbox, and other components.

  10. Control system: A control system that regulates the operation of the pelletizer, including the speed of the drum, the flow rate of the liquid spray, and other process parameters.

Advantage of Drum Granulator

Advantage-of-Drum-Granulator

  • Reasonable design, excellent material selection – with rubber engineering plastic as the lining, raw materials are not easy to stick to the cylinder, and play the role of anti-corrosion insulation.
  • High working efficiency – pellet rate of 90%, a small amount of return material, return material strength is small, can be re-granulated.
  • Low maintenance cost – through the steam heating, improve the temperature of the material, so that the material after autumn moisture is low, improve drying efficiency, save power consumption.
  • Strong practicability – suitable for cold and hot granulation and high, medium and low concentration compound fertilizer mass production
