Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.
Process technology. There are four stages involved in the production of iron ore pellets. These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets.
This chapter aims to provide an overview and the evolution of iron ore pelletizing process. One of them has been used in commercial production of iron ore pellets in China. View.
Iron Ore Induration. The term induration describes the hardening of a powdery substance. For example, in steel production, iron ore pellets are fed into melt furnaces. To avoid dusting and loss of ore, small oxide particles are agglomerated by sintering.
The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties.
In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it can be utilized, as opposed to disposed of. The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of

Jan 01, 2012· 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:
blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
KIOCL’s Iron Ore Pellets conform to international standards, making them ideal for hi-tech steel plants anywhere in the world. As a result of latest production techniques and constant Research and Development efforts and adopting innovative technology to improve quality, the KIOCL product is the choice of quality conscious
Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

Nov 26, 2014· Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.
Pellets: the process of pelletization enables converting Iron Ore Fines into “Uniformed Sized Iron Ore Pellets” that can be charged into the blast furnaces or for Production of Direct Reduced Iron (DRI). Pellets are uniform size, with purity of 63%- 65% contributing to
