SPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE

Usually, Iron ore fines and coal fines are introduced into the saggers in the form of separate concentric cylinders for reduction. The iron ore fines forms a hollow cylinder at the middle of the sagger and its outer surface and core is filled with coal fines as shown in Fig 4. The loaded saggers on the trolley enter the tunnel kiln for processing.
