In 2010, world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder.

• Lime kilns and coke oven plants are not included in the system boundaries for iron and steel production. This is bec ause the outputs of those plants ( lime and coke) are not CBAM goods themselves. Consequently, lime and coke are also not considered precursors for the calculation of the specific embedded emissions. •

The amount of these additives added are 5% of the mass of the iron ore. The mixture is mixed thoroughly inside a ball mill and transferred to a pelletizing machine. Once in the pelletizing machine, a level of moisture of approximately 9% is introduced by spraying water into the mixture. This will result in the formation of iron ore pellets.

Then the iron ore pellets will sent through metallic conveyor into the furnace to undergo heating process at 1200 degrees. After the heating process, the heated base mix will converted into a semi liquid cake. Using a sinter breaker machine the cake is break into small pellets. Finally these iron ore pellets under goes cooling in the cooling tower.

Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.

Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is ...
