iron ore pellets versus sinter in blast furnace
Iron ore (pellet, sinter and lump ore) is gradually reduced to iron in blast furnace The reductions are a serial of heterogeneous gas solid reactions that take place from the top of the furnace and throughout the shaft region of the furnace
What is the difference between pellets and sinter? - Quora
Jun 11, 2017 · 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).
Use of Iron Ore Pellets in Blast Furnace Burden – IspatGuru
Sinter, pellet and the calibrated lump ores are the three iron bearing metallics normally used in the blast furnace burden. Uses of all the three metallics in blast furnace burden can vary from zero to hundred percent with adjustment of the furnace parameters.
Which is better for the blast furnace process, sinter or ...
Oct 23, 2018 · A sinter plant processes fine-grained raw materials such as iron ore fines, coke fines (a.k.a. “coke breeze”), flue dust and scale pit scrapings, into much larger particles of sinter, suitable charging into the blast furnace. Sintering of fine particles into a porous clinker called sinter improves the permeability of the burden, making reduction easier.

Pellet, iron ore concentrste, sintered iron ore: buy from ...
Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process and is used for the production of pellets for blast furnaces and sinter. The concentrates are non-toxic, non-flammable and non-explosive. The concentrate is shipped as a bulk commodity by rail using the open-top rolling stock and by sea.
Recycling of Blast Furnace Dust in the Iron Ore Sintering ...
In iron ore sinter plants blast furnace dust and other fine-grained residues which are rich in iron or carbon content are recycled. The carbon contained in the blast furnace dust can be used to replace coke breeze which is added to the charge as fuel for the sintering process.
Iron ore pelletizing systems - liming
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. liming is the only supplier in the world that has both the Straight Grate and the Grate Kiln process for pelletizing.

Pelletizing - Wikipedia
The configuration of iron ore powder in a blast furnace is more tightly-packed and restricts the air flow. This is the reason that iron ore is preferred in the form of pellets rather than in the form of finer particles.
