Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. ... The mixing is done usually in vertical or horizontal high intensity mixers to achieve a homogenous blend of ore and additives.It is an agglomerating process of converting iron ore fines into 'uniformed sized iron ore pellets' which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.vertical-shaft-kilns for firing the pellets. Plant capacities were between 10,
