ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE …

iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of …

Effect of Bentonite on the Pelleting Properties of Iron ...

The physical and stone properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.

Bentonite - Wikipedia

Bentonite has been widely used as a foundry-sand bond in iron and steel foundries. Sodium bentonite is most commonly used for large castings that use dry molds, while calcium bentonite is more commonly used for smaller castings that use "green" or wet molds. Bentonite is also used as a binding agent in the manufacture of iron ore pellets as ...

Pelletizing - Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64%-72% Fe and various additional material adjusting the stone composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
