2 KILN BASED SPONGE IRON PRODUCTION PROCESS Rotary kilns are found in many processes that involve processing of solids. This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The ...
Pellets are heated, dried and indurated; with the majority used for in-house production of DRI. Direct reduced iron is produced by reducing iron ore pellets using non-coking coal in a rotary kiln. Pellet plant capacity at JCL is 0.6 million tonnes per annum. Recent News
Laboratory using a rotary kiln of 10.46 m long with 0.76 m internal diameter having a produc-tion capacity of 3-4 tonnes oil sponge iron per day. The details of pilot plant experiments using various types of ore lumps, heat hardened and green pellets with non-metallurgical coals as solid reductant are presented. ROTARY KILN—SOLID REDUCTANT
The inclination and the rotary motion of the kiln ensure that the raw materials move from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.
Plant overview Grate-KilnTM iron ore pelletizing system The first Grate-KilnTM system pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed. Since then, Grate-Kiln systems have been used for over 50 plants, on both magnetite and ...

The pellets produced by Xindia will cater, both to the domestic iron and steel industry and also to burgeoning export markets in China, Japan, Korea, which are largely dependant on imported Iron Ore to feed their blast furnaces and DRI (Sponge Iron) kilns. Pelletisation is a major process of agglomeration where micro fines, either in the form ...
Feb 14, 2017· The main raw materials for the production of DRI by the rotary kiln process are (i) sized graded iron ore or iron ore pellets, (ii) non-coking coal, and (iii) dolomite in small quantities to scavenge the sulphur. Iron ore of the right quality is the basic input for the coal based direct reduction process.
Iron Ore/Taconite. In the ironmaking process, the blast furnace or direct-reduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln. Many producers use a traveling grate and rotary kiln to heat the pellets to temperatures as high as 800°C to 900°C in the ...
It forms the grate-kiln system together with rotary kiln and annular cooler, which is an important part of the iron ore pellet production line. AGICO is a professional iron ore pelletizing equipment manufacturer. We provide traveling grates of different sizes according to customers' needs.
The pellet plant (using the grate kiln technology) is used to agglomerate and indurate iron ore fines into pellets, while the sinter making enables us to agglomerate iron ore fines into a coarse product, i.e. the sinter. Hard and semi-hard coking coal is heated in the coke oven facility which consists of two batteries containing 48 ovens each.

include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is …

Rotary kiln is a widely used equipment for iron ore oxide pellet induration. Preheated pellets are fed into rotary kiln for roasting. While tumbling in circumferential direction, pellets also slide forward along axial direction, exchanging heat with countercurrent gas and kiln wall. Fuel is injected into rotary kiln by burner and provides heat ...
Given the significant impact a rotary kiln burner has on the costs and revenues of iron ore pelletizing, that burner had better do its job well. The capital cost of combustion equipment is negligible in comparison to the capital cost of the plant. Yet, combustion performance is a major determinant of the pellet quality and
