• The pressure resistance of pellets formed by activated calcium bentonite addition is much lower than the pellets formed with Karben Sodium Bentonite. • Also, when Activated Calcium Bentonite is used as a binder alone, the wet pellet efficiency is also reduced. • Karben Pellet Bentonite is specially prepared for Iron Ore Pelletizing.

8 mm. HPS feed consists of iron ore as pellet feed fines, return fines and iron and steel work remnants, filter dust, additives and binders like limestone, dolomite, bentonite and coal dust. These micro pellets are fed onto a sinter machine to produce sinter cake, which is then broken down and smelted in a .

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. This chapter shows the status of the pelletizing process ...
