Magnetic Sinter Iron Ore

Influence of green pellet properties on pelletizing of

Magnetite iron ore green pellets are produced by balling moist concentrates to green pellets which are then dried oxidized to hematite sintered cooled and transported to steelmaking plants The existing theory for balling is based on the capillary theory but its applicability under industrial balling conditions is unclear
