straight gate iron ore pelletising process

straight gate iron ore pelletising process

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
