2. Introduction To Pelletisation Process Pellets are spherical balls formed by the agglomeration of natural or ground iron ore fines in the presence of moisture and binder These green balls of 5 – 20mm size are then dried, preheated and fired at 1250 – 13500 C Bonding is developed between the fine ore particles at such high temperatures …
Because of these processes, a fine granulometry is produced, and thus iron agglomeration process is necessary. There are several agglomeration processes including: briquetting, extrusion, …
Pelletizing iron ore fines is an agglomeration process that through a thermal treatment converts the ultra-fines fraction thereof into small balls ranging in size from 8mm (0.31 in.) to 18mm (0.71 in.), with adequate characteristics for feeding steel reduction works.
It is an important process of modern iron and steel complex. Iron ore powder agglomeration processes include sintering, pelletizing, and briquetting. The product from sintering process is called sinter, the product from pelletizing process is called pellet (Fig. 1), and the product from briquetting process is called "briquette."

Balling (iron ore pelletizing) FEECO can provide a family of solutions to meet your agglomeration needs. Whether you are looking to eliminate dust, convert a waste to a marketable product, or improve product characteristics, we can design and manufacture agglomeration equipment to create a highly efficient process that produces the product …
The most commonly employed agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets). Figure 1: Iron pellets The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way …
The process consists in: part of fine grained iron ore is transformed into 8–16 mm green pellets, while the rest and the coarse fine ores are mixed with fluxes, fuels and return fines, and then granulated …
The purpose of the iron pelletizing process is to convert the iron-rich fine-grained minerals into blast furnace charging material, which is defined as pellet, through agglomeration and hardening. ... pelletizing, indurating).

Agglomeration is a process of size,enlargement; btiquetteing,, sintering and ... The required properties depend on the type of ore and the quality requirement of pellets. The fineness is reported normally in terms of percent below 0.2, 0.075, 0.04 mm as well as its blaine number. The blaine number is a measure of specific surface area and ...
The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized …
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 …
Pelletizing is the most recent agglomeration process and was the result of the need to use fine concentrates of magnetite from certain iron ores. Iron ore pellets are produced by agglomeration of particles of less than 45 µm in size, forming pellets of from 8 to 16 mm, in disc or rotating drum.
Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted …
1. Introduction. Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are …
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …
