The iron ore sintering process is the second largest energy consuming process next to the blast furnace in overall integrated steel plant value chain. Sintering consists of two moving beds, namely a sintering machine, and an annular cooler. Once the sintering is completed, hot sinter is discharged on the annular cooler and air is blown from the bottom with …
