Influence Line In Pelletizing Iron Ore
Studies on the influence of a flotation collector reagent on iron ore
An iron ore pelletizing plant produces typically between 4 and 7 million tonnes of iron ore pellets per year, which corresponds to an hourly production rate of 500 to 900 t/h. Agglomeration is started by grinding and upgrading the iron ore to a concentrate with desired chemical quality and with a particle size distribution suitable for balling.

Influence of green pellet properties on pelletizing of magnetite iron ore
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.
