A sinter feed with good permeability from ignition until burn-through is required for efficient operation of a sinter plant. In this regard it is necessary to consider the widely held and simplistic view that sinter feeds containing iron ores with high ultra-fines content have low-pre-ignition permeability.

The bottom layer may vary in thickness from 30 to 75 millimetres (1.2 to 3.0 in). A 12 to 20 mm sinter fraction is used, also referred to as the hearth layer. The second, covering layer consists of mixed materials, making for a total bed height of 350 to 660 millimetres (14 to 26 in).
Sishen iron ore and fluxes where the coke, lime and return fines were all sized had the highest granulation effectiveness and permeability. The sintering properties of the mixtures in which the grain size distributions were controlled, were very similar for all the mixtures, but superior to the base case mixture in which the grain size

In this regard it is necessary to consider the widely held and simplistic view that sinter feeds containing iron ores with high ultra-fines content have low-pre-ignition permeability.
However the productivity of sinter decreased with a decrease in the size of iron ore.1) Many studies2–4) dem-onstrated that an increase of concentrate in iron ore blend reduced the productivity in conventional sintering. In this study, a number of commercial iron ore concen-trates were tested in a sinter pot to find their sintering char-

The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it
If FeO is less, sinter will be weak causing more fines generation & leading continuous to furnace hanging So, FeO should always be optimum. To improve the productivity and quality of sinter following requirements to be fulfilled Selection of raw materials Iron ore fines Size should be < 8 mm with Fe (T) = > 62% SiO 2 & Al 2 O 3

Dec 28, 2015· In 1902, W. Job invented the sintering of pyrite cinder and dusty iron ores with addition of coal and air blowing through the bed from bottom upwards (German patent number 137438). In 1905, EJ Savelsberg developed the process of iron ore sintering with the sintering mixture containing coal and coke breeze (German patent number 210742).
Q. sintering of iron ore 1. INTRODUCTION :- 40 to 50% iron ore becomes under size which may create pollution in the plant of the mine site. For the utilization of the variable ore, it is necessary to agglomerate the fines into the required size for charging in the blast furnace. Agglomeration is the size incensement process of the fines ore.

Jun 11, 2017· What is Pelletization? The process of Pelletization helps converting Iron Ore Fines into “Uniform Size Iron Ore Pellets” that can be fed in the blast furnaces or in the DRI kiln (DRI). Why Pelletization? Pelletization is the only answer to a major...
Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore mining volume.
