An organic binder, Funa, has been developed and used in the production of iron ore pellets for direct reduction in China. This paper mainly describes the effects of the binder on balling behaviors of magnetite concentrates as compared to bentonite binder.
12%Molasses was used as an alternative binder to the bentonite binder. The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated. Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentonite-added pellets…
The beneficial influence of viscous binders in iron ore balling is well known from everyday practical operations. The large variety of binders studied in the iron ore industry was recently reviewed by Eisele and Kawatra . The most common binder is bentonite, of which additions of 0.5–0.7% are usually made.
BASF IRON ORE BINDER TECHNOLOGY: EFFECTS ON PELLET SIZING. October 2019; DOI:10.5151 ... The shift to iron ore pellets has the advantage that they require less energy and labor per ton of …
possible to make pellets which meet the standards by adequate addition of type and amount of bentonite. Keywords: bentonite, pelletizing, iron ore concentrate, binder, sodium bicarbonate Introduction Major raw material in iron and steel industry is iron ore which can be classified as high grade and low grade in terms of its Fe content.
The effect of lime addition in hematite iron ore pellets on its physico-chemical as well as mechanical properties with respect to blast furnace requirement was studied in a laboratory scale with ...
For studying the effect of moisture content on the properties of green pellets, the amount of binder is kept constant at 0.5% and the specific area of iron ore fines is fixed at 1610 cm 2 /g and moisture content is varied between 8.0 and 9.5%. According to the capillary theory, at S (Liquid saturation) = , i.e. in the case of water ...
Molasses was used as an alternative binder to the bentonite binder. The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated. Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentonite-added pellets, and molasses ...
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 its acid constituents (SiO 2 …

Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentonite-added pellets…
pellets more competitively, using organic binders for agglomerating iron ore. The goals of this research were (1) to determine the physical and metallurgical pellet properties of pellets made with different types and dosages of organic binders and (2) to relate these pellet properties to the binder properties.

The iron ore was crushed, ground and screened to 100 # size and charcoal to 72 # size. Pellets were made by hand rolling method by using water and different quantities of binder. The pellets were fired at different firing temperature. Each crucible containing iron ore pellets were placed in a furnace
Effect of the Addition of Organic Binders on the Behavior of Iron Ore Pellets. Monica Speck Cassola, Arthur Pinto Chaves. ... This fact has been understood as a consequence of the dispersing effect of the chemicals. To check this hypothesis, a set of different kinds of organic dispersants were prepared to test on pellet feed, with the ...
