Get this from a library! Advances in rotary kiln sponge iron plant. [K K Prasad; Hem Shanker Ray] Annotation About the Book: Now that India is virtually the only player in this field, an elaboration is needed with respect to more fundamental understanding as well as future prospects and needs, ...
2D CFD model of rotary kiln of sponge iron process is developed to study the effects of angle of inclination, number of rotation and mass flow rate of iron ore on output parameters.
reduces iron oxide (ore) to iron. So, in a kiln, there are two sources of energy, one in the lance injecting coal particles from one end and the second is the coal in charge bed where reduction of iron ore occurs. The air tubes are located along the length of the kiln and they inject air into the kiln.

tunnel kiln sponge iron new technology. tunnel kiln sponge iron new technology As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of minerals...
Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln.
sponge iron from iron concentrate tunnel kilns. the coal ash and sponge iron, a product, remain separate inside the of Sponge Iron through Rotary of sponge iron will New Technology ( .
The iron ore is converted to DRI as it traverses along the length of the kiln. Hot product discharges from the reactor through a transition chute to the rotary drum cooler. The cooler is an inclined steel cylinder.
Inventorization of sponge iron plants brief description iron plant process total of a container in the tunnel kiln is about 80 hours tunnel kiln manufacturers nonconventional method of making sponge iron in the tunnel kiln process as compared to the old process..
Sponge iron production in rotary kiln The cooler is also inclined at 2. The largest improvements would be made by design modifications adopting a novel energy conservation scenario by process integration and thereby decreasing the coal and water consumption and by decreasing the cold fresh air.
SPONGE IRON PLANT. · Sponge iron being magnetic gets attracted and gets separated from non magnetic char. The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in predetermined ratio. The rotary kiln .
Sponge iron is the product generated by direct reduction of iron ore with aid of either carbon or natural gas under. controlled temperatures and pressures within a rotary kiln. However the performance of rotary kilns is usually. adversely affected by the formation of accretion.
6. The product Sponge Iron and semi burnt coal are discharged from the kiln through a rotary cooler. The cooler is 12M in length and water is sprayed directly as well as indirectly for cooling the material. The material is cooled down to 100oC and fed to magnetic separator for separating the sponge iron and nonmagnetic (char).
Mar 07, 1972· The sinter cake was subjected to the Micum drum test, which gave the minus 10 millimeter particle size as percent. Thus, a sufficient sinter strength is obtained. Reduction of this sintered material in a rotary kiln gave a sponge iron having a total iron content of percent and a zerovalent iron content of percent.
Tunnel Kiln, Tunnel Kiln Manufacturer India – Electrotherm. Quality of sponge iron made by the Tunnel Kiln technology is superior as compared to that made from the rotary kilns because, while the input raw material gets just about 24hours for the reaction, the figures almost reverse in case of the Tunnel Kiln.
Sponge iron is the product generated by direct reduction of iron ore with aid of either carbon or natural gas under controlled temperatures and pressures within a rotary kiln. However the performance of rotary kilns is usually adversely affected by the formation of accretion.
It enters the kiln at atmospheric temperature and thus, considered as it is in the model. (3) Generally, the outlet stream of the kiln consists of 82%, 10%, % and % sponge iron, char, spent lime and ash, respectively. As the amount of sponge iron is very high in the outlet stream of the kiln it is assumed as purely sponge iron.

China Capacity 100800 Tpd Rotary Kiln for Sponge Iron Kiln Design, Find details about China Rotary Kiln for Sponge Iron, Sponge Iron Kiln Design from Capacity 100800 Tpd Rotary Kiln for Sponge Iron Kiln Design Henan Hongke Heavy Machinery Co., Ltd.
Ring formation and heavy buildup in an experimental rotary kiln for production of sponge iron using hematite pellets, bituminous coal and nut coke have been described. The buildup from different parts of the kiln was visually examined and its mineral composition was studied in detail by microscopical and Xray methodl.
+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 The plant uses the coal based process in which pellet is reduced with noncoking type imported coal in a rotary kiln to make sponge iron.
