The pelletizing process is a process which contains numerous subprocesses, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in length, width, or height).

Abstract Factors affecting the bonding efficiency of bentonite during pelletising were investigated. Results show that it is influenced by the properties of bentonite, water and iron ore concentrate. The dosage of bentonite can be halved by exchanging cations in the interlayer to activate bentonite, removing bivalent cations to soften the water and milling the mixture to advance the contact ...

ABSTRACT This part reviews the goals of introducing organic binders into iron ore pelletization. Organic binders present a relatively small number of unique binding options but provide an extraordinary amount of flexibility in how to apply them. The key factors that lead into an effective organic binder are good dispersion into the iron ore, the ability to maintain the dispersion of the iron ...

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 transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

Usually, Iron Ore is manufactured and converted into Pellets. These are oval lumps of iron ore that are hardened using fuel. This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum ...
