Explore the iron and steel industry's use of iron ore, focusing on the pelletizing process of low-grade ores. Learn about the various sub-processes, including crushing, grinding, …
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
the percentage of iron ore pellets in blast furnaces has increased due to its uniform size, good reducibility, and high tumbler index. Pelletizing is energy-intensive and emits considerable CO
all pelletizing furnaces, ... pelletizing is being affected by price increase of power, oil, steel and commodities. ... This paper gives a brief evaluation of these themes related to iron ore ...
Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction (DR) processes.
Green pelletizing Outotec plants are normally using pelletizing discs in bigger plants, followed by roller screens. The green pellet quality and size distribution is paramount for the gas permeability of the pellet bed in the furnace and thus for product quality, energy consumption and process stability.
Outotec's scope includes basic and detail design for the indurating furnace of an iron ore pelletizing plant based on modern traveling grate technology. The indurating furnace is the core of the pelletizing plant, raw pellets are hardened in the furnace to enable further processing.
The expected decline in high-grade iron ore feeds urges leading engineering companies to focus on flexibility of steelmaking technologies towards the quality of inputs with blast furnace substitution and pelletizing cancellation in the pipeline.

Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes.
In order to comply with blast furnace and direct reduction demand, existing pelletizing plants are being improved and new projects are under evaluation and or erection.
CVIC Global is a leading supplier specializing in R&D, manufacturing, and sales of iron ore pelletizing and sintering plant equipment and industrial ceramics.
Primetals Technologies was chosen to design the core pelletizing plant, which encompasses mixing, green pelletizing, and product classification, as well as the circular induration furnace, an in-house development of Primetals Technologies.
Iron ore pellets are produced using a process called pelletizing. The raw material, iron ore fines or powders, is first blended to achieve the desired chemical composition.
