bentonite to bind iron ore into pellets and reduce the total amount of bentonite required for a given quantity of iron ore fines. Sodium in soda ash replaces some of the calcium and magnesium in the bentonite lattice and thereby improves the binding efficiency of Ca-bentonite. However, it was believed that bentonite would not

Jun 13, 2014· Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is the ...

• 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.

Apr 09, 2008· Thermal volume changes and oxidation mechanisms in magnetite iron ore green pellets balled with 0.5% bentonite binder, as a function of raw material fineness and pellet porosity, are shown. When a pellet starts to oxidize, a shell of hematite is formed around the pellet while the core still is .

Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources.

After making 8–10 mm pellet with requisite quantity of water, the pellets were coated with 50% of total iron ore fines using 0.5% bentonite in iron ore. Pellets were rolled in disc with simultaneous addition of water and bentonite containing iron ore fines. Thus, pure iron ore coating was made surroundings of the pellet.

The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet .

In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However ...
