What is Pelletizing?

Pelletizing is one of the processes that is available for enlarging particle size by granulation.

In general, the quality requirements for final agglomerates are: 

  • Size of the pellets
  • Green pellet strength
  • Moisture content of the dried pellets 
  • Compressive strength of the dried pellets

How does Agglomeration work?

The physics behind agglomeration is based on a three-phase system consisting of the dry feed material, air and water. The predominant forces in this system are capillary forces. Binding agents have to be used as additives, as in most cases, water alone does not generate sufficient binding forces between the particles. There are various organic and inorganic additives available on the market for producing both green and dried pellet qualities that match the given requirements.

The Pelletizing Disc

Agglomeration itself takes place in the pelletizing disc. There are multiple process parameters that influence the disc product. In order of importance, these include disc inclination, disc speed, wall height, position of the water nozzles and position of the feed to the disc. Producing pellets that fall within specifications can become a challenge that calls for experienced operators who know how the different parameters can influence the process.
