Iron Ore Pelletizing Essential in Meeting Future Steel Needs
As the needs of the steel industry change, one production component looks to be increasingly important in meeting the needs of the modern steel industry: the pelletizing of iron ore. Iron ore pelletizing , or balling , is the process of transforming fines into spherical granules anywhere from 8 – 16mm in size via tumble-growth (agitation) agglomeration using either a disc pelletizerIron Ore Pelletizing Process: An Overview | IntechOpen,11-07-2018· The final use of iron ore pellets in ironmaking reactors requires minimum mechanical properties. Pellets must withstand tumbling and falling during transport and mechanical loading inside the reactors due to the charge weight.
