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 ...
FLOFORM™ Iron Ore Pelletization FLOFORM™, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at 0.01-0.05% prior to balling, i.e. about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
Nov 14, 2011· Kemira has developed a series of KemPel™ synthetic organic binders for iron-ore pelletization. The technical and commercial benefits of this technology were presented in August to the Advanced Sustainable Iron & Steel Making Center (ASISC) conference at Michigan Technological University in Houghton, Michigan.

during pre-heating, contrary to bentonite clays commonly used in pelletizing iron ore for blast furnaces. Due to the need to process increasing volumes of low grade iron, interest in organic binders has increased lately. Organic binders tend to produce good quality wet pellets which however often lack in compressive strengths after sintering.
Jun 10, 2011· 1. Introduction. Bentonite is the conventional binder in iron ore pelletization and used at 0.5–1.5% addition levels in the pellet feed by weight of iron ore,, .It controls the moisture of iron ore concentrate in the pellet feed and improves physical properties of .
Organic binders have been used as an attractive alternative to bentonite in iron ore pelletizing process, mainly because it burns without leaving any residue in the final pellet. There are two main types of organic binders, those based on cellulose compounds and other based on polyacrylamide polymers.

Fine-sized concentrates are not suitable to be directly used in the iron-making facilities. Hence, an agglomeration technique should be applied and the most commonly employed method is pelletization. In pelletization, iron ore, water and a binder are balled in a mechanical disc or drum to produce agglomerates. Bentonite is the most widely used ...
