Iron Ore Fines Plant Techniques
PROCESS BRIEF
Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at the Sinter Plant, which forms 7080% of iron bearing charge in the Blast Furnace. This entire process of sinter making is associated with various safety hazards like hit / entanglement with mobile equipment, burns, fire, slip fall, exposure to dust, smoke ...
