    Introduction to Iron ore Pellets and Pelletizing processes

    Formation of green balls or pellets Green pellets with a size range of 8 mm to 16 mm are prepared in a balling drum or in a disc pelletizer. Disc pelletizer is preferred for the production of the quality green pellets since in the disc pelletizer it is easy to control the operation with minimum of foot space. The disc pelletizer is an inclined pan having around 5 metres (m) to 7.5 m

    Balling drums Metso. The balling area is where the powdered ore is mixed with water and rolled in rotating drums to create spherical balls. The green balls are spherical agglomerates nominally 12.5 mm in diameter, formed by rolling a moist mixture of finely ground iron ore concentrate, binder and sometimes a flux.

    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. Both straight grates
