Method for Calculating Yield of DRI Production in Rotary

Dec 16, 2010 we would like to know the correct method for calculating the yield for working the production of Sponge Iron in a rotary kiln. we have been evaluating the yield for production using the following formula : P = (Q-%TM)X(% Fe (T) in ore % LOI 1 / 2 % L&P) where. P = Production, Q = Qty of ore used in the Kiln. Fe (T) = Total iron in the ore,

SPONGE IRON PLANT

Iron ore crushing is not required since sized material has to be purchased. Iron ore of size 5 mm to 20 mm is being used for the production of Sponge iron. Iron ore is being fed to the Ground hopper, from where it conveyed to the Screen with the help of Vibro Feeder, where Oversize i.e. + 20 mm and Undersize i.e. 5

Sponge Iron an overview ScienceDirect Topics

DRI, also known as 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 oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H

Sponge Iron Production Process Arij Trading

In this method, heat coal (as a reducing agent) is mixed with iron ore and sponge iron is produced in a horizontal furnace. Input iron ore: In the Midrex or HYL process, it is generally recommended to use high quality cooked pellets with a maximum of about 30% iron ore lumps.

Direct reduced iron Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

SPONGE-IRON Shakambhari Group

In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850°C -1,500°C).
