摘要： A processed DRI material having an average surface roughness (Ra) of less than 1.5 μm is disclosed. A method and system for making processed DRI are also disclosed. One embodiment of the method and system may include assembling a rotatable chamber having an internal screen capable of supporting DRI during tumbling, with at least one opening in the chamber to permit fines to exit the chamber during tumbling, and delivering DRI into the chamber to tumble the DRI on the screen to remove fines from the DRI. Another embodiment of the method and system may include assembling a rotatable chamber having a feed end and an exit end, and having a screen therein capable of supporting DRI as the DRI moves through the chamber, and delivering DRI to the chamber and rotating the chamber to tumble the DRI while removing fines.
