An iron ore pelletizing plant is typically comprised of a series of unit operations in a specific process sequence. It can be divided into: Feed preparation Mixing (Iron ore + additives) Balling ("green" pellets are produced) Indurating (firing and hardening and producing the "fired pellets")
INDURATED IRON OXIDE PELLETS ARE MADE BY AN IMPROVED PROCESS COMPRISING OXIDIZING GREEN PELLETS FORMED FROM FINELY DIVIDED IRON OXIDE SOLIDS AND FINELY DIVIDED REDUCED IRON SOLIDS.
iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an
Technological advancements in steel production machinery, along with prevalent environmental concerns, are boosting the adoption of iron ore pellets for the carbon-less steelmaking process....
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:
Pelletizing normally has four processes: (i) receipt of raw materials, (ii) pretreatment, (iii) balling and (iv) induration and cooling. Receipt of Raw Materials: The location of a pelletizing plant affects the method of receiving raw materials such as iron ore, additives and binders (bentonite, clay, hydrated lime, etc.).
During pelletizing, ore powder is rolled into iron ore green pellets in rotating drums together with water, binding agents and additives. Globules with grain sizes of approx. 15 mm are produced, which are then baked into porous …
Vale is the world's biggest producer of iron ore and pellets, raw materials essential to the manufacture of steel. ... In addition, we have a pelletizing plant in Oman and stakes in joint ventures in China that produce pellets (small lumps …
Iron ore processing is divided into two categories based on the product of iron ore production and the production of iron ore concentrate is divided. The production of granulated iron ore is generally done dry and without water.
A trend toward pelletizing iron ore at the steel plant site may be developing. This evolution would probably result in utilizing various blends of ore feed which could have wide variations in their grindabillty. Effect on Pellet Quality Good pellet quality depends on a large number of variables many of which are inherent in the ore.
The pelletizing process involves the preparation of raw materials; the proportioning and mixing of raw materials; the formation, preheating, and firing of green balls; and the cooling of the fired pellets. With the dramatic increase in pellet production, considerable progress has …

Modern iron ore pelletizing process operations may be divided into two main process sections: feedstock preparation and agglomeration processes. In most plants, the required particle size distribution (PSD) is obtained through the wet ball mill circuit.
An enrichment of iron ore can be achieved by separating unwanted components. This enrichment of iron ore represents a significant process step in steel production. During the concentration, most of the gangue is separated. This reduces transport costs and increases the production rate of the blast furnace and direct reduction plant.
The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is …
There are several iron ore pelletizing processes/technologies which are available for the production of the pellets. Some of these are (i) shaft furnace process, (ii) straight travelling grate process, (iii) grate kiln process, (iv) …
Iron Ore Pelletizing Process: An Overview 1. Introduction. Iron ore and iron ore pellets are important sources of iron for manufacturing steel. …
Pelletizing First, moistened concentrates are fed to a rotating drum or an inclined disc, the tumbling action of which produces soft, spherical agglomerates. These "green" balls are then dried and hardened by firing in air to a temperature in the range of 1,250° to 1,340° C (2,300° to 2,440° F). Finally, they are slowly cooled.
Description This book is a reference in the knowledge of iron ore pelletizing. He deals with various aspects from raw materials for pelletizing, processes, equipment, technologies, effect of additives on the m...
The pelletizing discs used for agglomerating iron ore concentrates into pellets are remarkable for their very narrow particle size distribution with a target size of 10 – 14 mm, important for …

Our heavy-duty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
