They enter the rotary kilns through a feed chute and are initially pre-heated with the liberation of heat from the volatiles from the coal in the first 1/3rd of the kiln. The reduction process begins after this where the iron oxides are reduced to metallic iron. The following chemical reactions take place inside the kiln. C + O2 = CO2 CO2 + C = 2CO
The present work identifies the basic features of burden movement in a rotary kiln. The cold model study was conducted with iron ore as the feed material to determine the influence of length to diameter ratio (L/D) of a rotary kiln on the filling degree, hold-up, and residence time of the charge. An empirical equation correlating different operating variables has been derived on the …

So far CITIC HMC Co., Ltd has successfully carried out many projects in China, such as Guangqing in Guangdong Province, Dingxin in Fujian Province, Qingshan in Zhejiang Province, Linyi in Shandong Province, and more.
It involves reducing iron ore into a solid form called sponge iron which has a high iron content and porous structure. This is done through reduction in a rotary kiln or a fluidized bed reactor using natural gas or hydrogen. The solid iron can then be melted in an EAF. ... H2-based DRI plants need a continuous supply of hydrogen. In the case of ...
Sponge iron rotary kiln is mainly used to extract sponge iron ore. Sponge iron is a good direct reduction iron ore, which has the characteristics of non pulverization, high activity, high compressive strength and low carbon content. It can replace scrap steel as the main raw material for electric furnace steelmaking, and is widely used in metallurgy, steel, building materials, …
Raw material utilization and waste generation for the DRI suggest that 1.6 tonnes of ore,1.2 tonnes of non-coking coal and 0.05 tonnes of dolomite are needed to produce 1 tonne of sponge iron and 0.2 tonnes of solid wastes [2, 5].This implies that for every 10 tonnes of sponge iron produced, almost 2 tonnes of solid wastes are produced in the form of semi …
3.1.1 SPONGE IRON PLANT M/s BSPL is now operating 2 DRI kilns, each of 100 TPD capacity for production of 60,000 TPA sponge iron. The company is now planning to install (1x200 +1x350) TPD DRI Kilns for production of 1,65,000 TPA Sponge Iron. So, the final will be 2,25,000 TPA Sponge Iron. Manufacturing Process
SIPL is operating 4 x 100 TPD Direct Reduced Iron Rotary Kilns for production of 2000 TPA Sponge Iron at Purulia, using the proven German SL/RN technology. Sponge Iron, also known as Direct Reduced Iron is produced from Hematite Iron ore (5 to 18 mm size) by removing the oxygen by direct reduction process using non coking coal as the fuel and ...
Sponge Iron or Direct Reduction Iron (DRI) refers to a porous metallic substance that is produced by the direct reduction of iron ore, where oxygen is removed from the iron oxide using coal or natural gas as reductants and dolomite as a desulphurizing agent [7]. Raw materials are fed into the rotary Kiln by a conveyor to generate fugitive dust
