    Tunnel Kilns can use soft ore; Tunnel Kilns can comfortably work with Iron Ore fines (</= -5mm) Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln. Reaction time of 42 hours in the Tunnel Kiln

    tunnel kiln process of iron ore reduction

    Tunnel Kiln Electrotherm Engineering & Technologies. Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9% purity. When iron ore is mined or processed (in a crusher), lots of fines are generated. Quantity of fines generation is a function of the quality of ore i.e. whether it is hard or soft.
