Pelletizing of iron ore produces spheres of typically 8-18 mm (0.31-0. In) diameter. Raw materials are rolled into a ball, then fired in a kiln to sinter the particles into a hard ball.
ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements leads to the …
1.3 Charging the blast furnace/ BOS plant. Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux ...
Thus, in iron ore pelletization, class C and class F fly-ashes may both undergo pozzolanic reactions. Fly-ashes which do not meet ASTM C618 may still be useful as pellet binders, so long as they are pozzolanic. These fly-ashes are generally disposed of in landfill as solid waste, as they are unsuitable for use in construction materials or cement.
Agglomeration is the process of converting iron ore fines into easily handled size and shapes as required in blast furnaces [1]. In the pelletization process, fine materials are rolled with water ...
The iron-ore fines (bulk sample) of −10mm size fraction shown in Fig. 1 were collected from a mine in Barbil region, Keonjhar, Odisha for conducting the scrubbing and pelletization study. The detailed mineralogical, physical, and chemical characterization studies by optical microscopy, X-ray diffraction (XRD), Fourier-transform infrared …

The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: .
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
FLOFORMTM, an alternative. 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 FLOFORM (0.02 to 0.03%) and bentonite ( 0.2 to 0.33%) in the addition range could also give excellent results thus ...

Claremboux et al. [14] and Sivrikaya et al. [15] studied on different organic binders in iron ore pelletization and concluded that these binders incorporated sufficient properties in iron ore pellets.
The goals stemming from the final reduction process are drawn back through the pelletization process to present a clear rationale for why each material can be used to control the pellet quality. Major inorganic binders such as bentonite, colemanite, and lime are examined along with less commonly used alternatives.

This paper summarizes more than a decade of systematic studies of the flow field in an iron ore pelletizing rotary kiln using computational fluid dynamics (CFD) on simplified models of a real kiln. Physical, laser-based experiments have been performed to validate part of the numerical results. The objective is a better understanding of the kiln …
The iron and steel industries in India are vitally concerned with agglomeration of iron ore fines. Indian iron ores are relatively soft and friable; during mining and sizing processes around 30-40% fines (particles below 8 mm size) are generated. The ore washing plants also generate around 5 million tonnes of slimes per year.

lumps in total iron ore production has been about 40 % with the rest being accounted for fines and concentrates. Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the feed. Moreover, the excessive fines generated from the iron ore crushing units are mostly stored as waste.

Raw material preparation – During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is ...

50 Iron Ores and Iron Oxide Materials. Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.
