What is Pelletizing?
Pelletizing is used throughout a multitude of industries to process thousands of materials from difficult to handle powders and fines, into easy to handle pellets. With many benefits, and a highly customizable process, pelletizing has become a staple in many industries, with new applications for this valuable process constantly on the rise.

Optimization of pelletization process conditions and binder
Moreover, pelletization operating conditions were also optimized using pelletization force (3000–4500 N), die temperature (90–110°C) and relaxation time (15–60 s) while the die diameter was constant at 6 mm. The pellet quality improved with higher die temperature and pelletization force, but the effect of holding time is insignificant.

Iron Ore Pelletizing Process: An Overview
Additionally, the sintering of ore grains also happens, leading to the development of mechanical strength. This sintering may be caused by solid state interaction of particles, but also with the presence of liquid phase, which can act as transport media increasing the sintering rate. The liquid phase also acts as bonds among ore particles.
