  • Iron Ore Pelletizing Process: An Overview

    Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

    Aug 01, 2018  During the pelletizing process, the iron ore is converted into a powder through a three-step crushing stage, then mixed with additives and a specific binder, and eventually rolled into green pellets in rolling drums. The 9–15 mm (in diameter) “green” pellets are then to be sintered in an induration machine [ 2, 3 ].
