MIDREX® Process - Midrex Technologies, Inc- Iron Ore Pelletizing Process: An Overview | IntechOpen

as it is an oxidation process. The hardening of pellets can be done by the vertical shaft kiln or travelling grate furnace cum rotary kiln. The vertical shaft kiln needs lower investments &is suitable for small capacities of 100 simulating the reduction zone in gas-based shaft furnace direct reduction processes. The reduction degree is the highest when reduced with the gas composition of HYL-III while the lowest when reduced with DPCG.Plant overview Grate-KilnTM iron ore pelletizing system The first Grate-KilnTM system pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed. Since then,
