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 firingJul 11, 2018 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 formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firingIron Ore Pelletizing Process: An Overview IntechOpenAug 01, 2018 During the pelletizing process, the iron ore is converted into a powder through a threestep 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 ]The effect of disintegrated ironore pellet dust on
