Bentonite is the most widely used binder in iron ore pelletizing. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet qualities, however, because of its acid constituents (SiO 2 and Al 2 O 3) it is considered as an chemical impurity especially for
China Bentonite for Iron Ore Pellets Binder, Find details about China Bentonite For Iron, Bentonite from Bentonite for Iron Ore Pellets Binder Zhe Jiang Fenghong New Material Co.,Ltd.
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 and Al 2 O
#0183;#32;The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content. Therefore, alternative binders to bentonite have been tested. Organic binders are the most studied binders and they yield pellets with good wet
765 bentonite for iron ore pellets binder products are offered for sale by suppliers on, of which bentonite accounts for 1%. A wide variety of bentonite for iron ore pellets binder options are available to you, There are 6 suppliers who sells bentonite for iron ore pellets binder on, mainly located in Asia.
#0183;#32;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
#0183;#32;1. Introduction. Iron ore pelletization plants in the United States used approximately 612,000 metric tons of bentonite as a binder to produce iron ore concentrate pellets in 2000 (Virta, 2001).It is a major cost item, with individual plants spending US35 million annually for bentonite.
#0183;#32;The iron ore fines (Fe: 64% and LOI: %), anthracite coal, bentonite and limestone are taken as the pellet feed material. The aim of the present work is to investigate the effect of additives (bentonite, limestone and anthracite coal) variation (,, and 1%) on the physical, chemical and mineralogical characteristics of fired pellets prepared from high grade hematite fines.
Bentonite clay has traditionally been used as a binder to make iron ore concentrate pellets, but it is expensive and contaminates the pellets. Organic binders may be a viable alternative to

Sodiumactivated calcium bentonite is used as a binder in iron ore pellets and is known to increase strength of both wet and dry iron ore green pellets. In this article, the microstructure of bentonite in magnetite pellets is revealed for the first time using scanning electron microscopy.
1) The bentonite binder use in metallurgy pellet binder for iron ore pellet, can be used in a variety of fine iron ore sand bond pellets. The product can obviously increase raw pellet strength and ruptures temperature to expand roasting area, the permeability of raw material layer is good, and improved pellet quality, reduce cost, can obviously increase the economic efficiency of Iron and
#0183;#32;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, bentoniteadded pellets, and
Bentonite is considered as a chemical impurity for pellet chemistry due to acid constituents (SiO2 and Al2O3). Especially addition of silicaalumina bearing binders is detrimental for iron ore concentrate with high acidic content. Organic binders are the most studied binders since they are free in silica.
alternative binders to bentonite for iron ore pelletizing: part i: effects on physical and mechanical properties The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content.
The physical and chemical 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.
