Sponge iron is a raw material used to produce steel. It is also known as direct reduced iron (DRI). It is produced by directly reducing an iron ore pellet or lump in a solid state using a reducing gas. The reducing gas can be made from natural gas, coal, or hydrogen. The DRI is cheaper than pig iron, and it is less polluting.
Sized iron ore will be used for the production of sponge iron in DRI plant. The Iron ore should be of high grade to ensure that the sponge iron produced contains low gangue materials and is suitable for use in steel making. The iron content of the ore should preferably be around 62 to 63%.
Single-toggle jaw crushers are used for the simplicity of design, where the movable jaw moves at the top of the crusher. The rotating shaft connects the two jaws; the moving jaw presses the material against the stationary jaw. On the contrary, Blake jaws crushers vs gyratory crushers, the bottom is where the moving jaw is pivoted in the …

the sponge iron. The reduction process consists of two procedures, which are primary reduction (solid carbon reduction) and secondary reduction. The primary procedure mainly includes: (iron ore, rolled steel scales, etc.) → Drying → Magnetic Separation → Crushing → Sieving → Canning → Entering Primary Reduction Furnace → Sponge Iron.
Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers …
This type of impact crusher can be used in any stage of the crushing process. As per the working principle of Impact / Hammer crushers, they can be classified into two main types. Horizontal shaft impact (HSI) crushers. Vertical shaft impact (VSI) crushers. Now we have discussed the basics of different types of crushers.

Rungta Mines Ltd produces iron pellets with cold crushing strength (CCS) of 210+ and porosity of 24+. For More Specifications, Call us at . ... Better tumbler index of pellets allows it to be used as a substitute of lump ore in the production of sponge iron and in blast furnaces.
Sponge iron is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron Ore Pellet is used for reduction. After the reduction of iron ore pellet, the product resembles a sponge because of pores left behind after the ...
The reduced iron particles embedded in the viscous sludge into nodules called luppen . The product is discharged from the kiln and is cooled and crushed.
Presently, most of the coal based sponge iron plants in India, use iron ore lumps. The requirement is generally 1.6 to 1.8 t/ t of sponge iron. These high requirements are mainly due to the fines generated in handling the purchased ore from the sources to the plant. This reduces the kiln campaign length and increases the loss of ore fines.
Sponge iron is considered more environmentally friendly due to its lower energy requirements and lower carbon emissions compared to pig iron production, which is energy-intensive and has higher carbon emissions. 13. The quality of sponge iron, with fewer impurities, makes it suitable for producing high-quality steel.
In the conventional process, the sponge iron leaving the rotary kiln at 1,020 °C (Dey et al., 2015) is cooled to 110 °C for two reasons: (i) to prevent re-oxidation of the sponge iron when ...

The crusher is used in industries where the amount of swarf is an issue and before long swarf should be centrifuged or briquetted. The crusher is intended for the following types of turnings: •carbon steel •stainless steel •other alloyed steel with tensile strength up to 1.200 N/mm2 (174,000 psi) •aluminium alloys •sponge iron •titanium
Rourkela and Sundargarh area is renowned for Sponge iron manufacturing business and is a big hub for sponge iron supply. There are about 107 sponge iron units in the cluster and majority of industries located in Sundargarh area engaged in production of sponge irons which further converted into billets through induction furnace for further use.
Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron.
