What is agglomeration in metallurgy?
Balling is a specific type of agglomeration used primarily in the iron ore industry. It involves the formation of small balls, known as green balls, from finely ground iron ore concentrates or powders. The green balls are typically created by adding water or a binder to the ore fines and agglomerating them in a balling drum or disc.

Iron ore pelletizing
If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended together in a mixer and fed to balling discs or drums to produce green pellets of size typically about 9-16mm. The green pellets are then fed to the induration machine.
Iron Ore Agglomeration Techniques and its Historical …
Rotary drum agglomeration, also known as balling drums, has been employed for iron ore agglomeration since the 1950s. This technique involves the tumbling of iron ore fines in a rotating drum with the addition of a liquid binder. As the drum rotates, the fine particles adhere to one another, forming larger agglomerates.
