An indurating furnace has a heating station and an air passage leading to the heating station. A draft of preheated recirculation air is driven through the passage toward the heating station, and is mixed with fuel gas to form a combustible mixture of preheated recirculation air and fuel gas that ignites in the passage. This is accomplished by injecting the fuel gas into the passage in a ...

concentrates, pellets have become an important feedstock for blast furnaces and direct reduction furnaces. The most common pelletizing methods in the world are the straight grate and the grate-kiln technologies. Other technologies, such as shaft furnaces or the production of cold-bonded pellets play only a marginal role.

Plant operators would either feed more energy through the burners, usually in the form of fossil fuel, to maintain the uniformity of the firing. If the addition of more heat is not possible due to limitations of the furnace, they would need to reduce the speed of the travelling grate with a direct impact on the productivity of the plant.

The pelletizing plant includes drying and grinding, mixing, green pelletizing, pellet induration section and pellet screening section. In induration section, the indurating hood is the main part of a pelletizing plant for iron-ore fines. It serves for drying, heating and cooling of the pellets.

Indurating Furnace Process Indurating Furnaces are rectangular/ oval shaped furnaces and are specifically used to produce iron ore pellets. Raw pellet needs to be baked to give them sufficient mechanical strength to withstand further handling during transportation and charging to a blast furnace or to a direct reduced iron furnace.

Nov 09, 2005· FINLAND - OUTOKUMPU TECHNOLOGY has signed a contract worth US$200 million to supply the world's largest pellet indurating furnace to SAMARCO MINERACAO of Brazil. The new furnace will be operational at the end of 2007 in Samarco's iron ore port in Ponta Uba, Espirito Santo. The furnace will handle 7.25 million tonnes of iron ore per year.

In the Kiln, pellets are brought up to final indurating temps. Rotation of kiln exposes entire pellet bed to heat radiating from the burner resulting in uniform pellet quality. The kiln burner utilizes cooler off gas to heat material bed to nominal of 1200-1340 °C completing the slag bonding and mineral bridging to …

Iron ore pellets are superior to iron ore lumps in the subsequent iron making processes such as Blast furnace, DR furnace etc. Iron ore pellets with a nominal 64- 67% ... Iron ore pelletizing - . Iron ore pelletizing. Iron ore fines are agglomerated into pellets and then indurated using a …

Three systems are used for indurating pellets, i.e., a shaft furnace system, a straight grate system and a grate-kiln-cooler system. Shaft furnaces are the most traditional facilities; however, few plants use this system these days because of their limited scale. A straight grate system emerged in the industry soon after the shaft furnaces.

The energy required for firing the pellets in the indurating furnace comes from two sources. The pellet composition provides a large part of the fuel either with the addition of carbon in the pellet material or from the exothermic reaction coming from the change of phase of the ore in the firing process (for instance with magnetite ore).
