The pellet ore is divided into acid pellet ore and alkaline pellet ore. Since acid pellet ore production and operation is easily controlled, and the pellet has high grade and intensity, and blast furnace also need both acid pellet ore and high alkalinity sinter ore for smelting, so various countries mainly produce acid pellet ore.
The iron blast furnace (Fig. 47) is the most highly developed shaft furnace and can operate very efficiently not only as a heating unit but as a high temperature reaction chamber.Modern furnaces are nearly 30 m high (plus a considerable superstructure) and may be over 15 m in diameter at the hearth.

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.
A brief introduction to recent developments in iron ore pelletizing is provided in this chapter, including the world output of fired pellets, pellet production processes, preparation of pellet
Blast furnace or shaft furnace feed should form a perme-able bed of material, permitting gas ﬂow through it uni-formly at a high rate. Iron ore concentrates in the form of ﬁnes are not suitable because, ﬁnes tend to pack into a non-permeable bed and also they are likely to be carried away as dust by the high gas ﬂow rates.
shaft furnace iron ore pellet. Research of A NewStyle Roasting Shaft Furnace of Drawing lessons from the field of iron and steel pellet roasting shaft furnace,a newstyle vanadiumtitanium magnetite ore or coal sodium oxide roasting furnace is put forward
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of
Jul 10, 2017· 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 ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing
Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.
