Iron ore pellets. Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of direct reduced iron (DRI) and in blast furnaces for the production of hot metal.

From the test result it was clear that pel-let properties were inﬂuenced by the bonding phases present in the pellet. The tumbler index increased
The Tumbler Index is a relative measure of the resistance of the material to breakage or degradation by impact. (ii) Abrasion Index: It is a relative measure the degradation of iron ore by abrasion. The Tumbler Index and Aibrasion Index are determined in a tumbler test apparatus as per the Bureau of Indian Standard No. 6495

Pellets. Pellets are a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of sponge iron and in blast furnaces for the production of hot metal.
bond in pellets. The developed sinter shows good shatter index (92%), tumbler index (67.5%) abrasion index (7.5%) and reducibility index (70%) and low reduction degradation index (27%), which are compara-ble with the conventional iron ore sinter made in the same set-up keeping other condition identical. This
Jan 15, 2019· Experimental studies on attrition and dust generation of iron ore pellets have included the tumbler test used to calculate the Abrasion Index, which is a test suggested by the International Organization for Standardization (ISO3271: 2007) and routinely used by pellet producers in the quality control of iron ore pellets ; dust towers  and ...

higher values of tumbler index in all the iron ore lumps except Serazuddin (previous) and Khanda Bandha OMC Ltd.. For all the fired iron ore pellets, the degree of reduction in coal was more intense in the first 30 minutes after which it became small. Slow heating led to higher degree of reduction in fired pellets than rapid heating. All the iron
PELLETS: With gradual depletion of high Iron Ore reserves, the Iron and Steel sector world over has been looking at alternatives to utilise the low grade iron ore fines for iron making so that there is optimal utilisation of the available iron ore resources.

If pig iron and steel prices can rise by $15-20/mt it may be better to limit additional pellet sales, as the steel price would cover the increase in the pellet premium. Russia's larger iron ore miner Metalloinvest shipped 58% of its iron ore pellets externally in 2016, while in Q3 2017, external pellet sales had fallen to 48%.
Today iron ore agglomeration is the largest tonnage application for sintering, with plants operating at up 20,000 metric tonnes per day. For example, Figure 2.14 is a picture of a modern agglomeration facility which incorporates off-gas capture to reduce environmental damage. In such a facility, the iron ore fines are mixed with fluxes, carbon fuel, and water.

Advantages of Pellets. 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 same both in the blast furnace and for DR production. Pellets have good reducibility since they have high porosity (25-30%).
Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder that is generated during the ore extraction process, once considered waste. The pellets are used in the production of steel which is used in the construction of bridges, cars, planes, bicycles, appliances and much more.
