Iron Ore Sponge Iron Rotary Kiln

Coal Based Rotary Kiln for Direct Reduced Iron Sponge Iron 100 TPD, 350 TPD, 500 TPD Solid state reduction of Iron Ore using either coalgas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron DRI. Since DRI is produced by removing oxygen from iron ore, its structure is just like sponge with a network of connecting pores.
