Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion up to 40 of 150 m micro-fines in iron ore fines, which makes sintering difficult.

Iron-bearing dusts, containing valuable constituents such as Fe, CaO, MgO, C, etc., are generally utilized as raw material in iron ore sintering. However, the dusts characterized by low granulating and refractory performances always lead to negative effects on sintering indexes.
sintering process iron ore pelletizing. Pelletizing Process. include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze fuel.
Technologies for improvement in Sintering Process. Sintering of iron ore is a metallurgical process carried out on a sintering machine. It is basically a pre-treatment process step during iron making to produce charge material called sinter for the blast furnace. It is an agglomeration process achieved through combustion.
raw material preparation step is iron agglomeration, or iron ore preparation, where the iron ore fines obtained from the mining process are heated 1300-1480 186C and melted into pellets to be fed into the BF.
The sintering of fine ores can also be a polluting process, and mills under environmental constraints may favor direct-charge ore such as lumps or pellets.
Sintering Process Steps and DEfinition Process steps of Sintering 1. Mixed iron ores, additives and solid fuel on a grate Sinter mix 2. Suction is applied beneath grate 3. Top of bed is ignited, hot gases are drawn into it 4. Air is sucked down through bed 6. Sinter mix is agglomerated into big pieces 7.
Description. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Due to the depleting reserves of traditional high-grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia.
Composite agglomeration process CAP of iron ore fines has been proved an effective route for ironmaking burden production, and is characterized by low the fuel consumption and high the productivity compared with the traditional sintering process. Sintering behavior of pelletizing feed in CAP has not been studied fully yet.
ore roasting or sintering, including pelletisation is to be included in the ETS. Table 1 gives an overview of the NACE classification of this Annex I activity. Table 1 Classification of the iron ore industry according to the Annex I of the amended Directive and corresponding activity in NACE Rev. 1.
Iron ore pelletizing, or balling, is the process of transforming fines into spherical granules anywhere from 8 16mm in size via tumble-growth agitation agglomeration using either a disc pelletizer pan granulator or rotary drum.
The proper design of a rotary dryer is based upon several key fac tors.
