Iron ore pellets are small and hard spherical particles agglomerated from a fine iron ore concentrate. They are used in the blast furnace process to produce hot metal. The diameter of blast furnace pellets is usually between 8 and 16 mm. In this study, a batch of magnesia iron ore pellets was first sieved into particle sizes of 8–10 mm, 10–12.7 mm, 12.7–16 mm and 16–20

Iron ore crushing is now mostly done in iron ore processing workshops and in self-braking and semi-self-breaking Asian countries instead of classical Asia (rod-pellet). In autochthonous Asians, the extracted stones enter autochthonous Asia directly after the first stage of crushing, and the coarse grains crush other particles as they break down.
