Feb 14, 2017 Normally for rotary kiln process volatile matter is to be in the range of 25 % to 30 %. Coals for direct reduction in the rotary kiln need to have low swelling index. Normally swelling index is to be less than 1. The physical and chemical specifications of the non-coking coal are as follows. Size of lumps – 5 mm to 20 mm

Sep 10, 2020 In the newly designed sponge iron rotary kiln system, a coarse coal branch pipe and fine coal branch pipe are added at the kiln head. The original way of adding 100% coal at the kiln head is changed to 50-70% coal is added together with fine iron ore and dolomite through the mixing mode at the kiln tail, and the remaining 30-50% coal is added

Rotary Kiln with SL/RN Process. Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, and 500 TPD) Solid-state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from

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

Aug 03, 2011 During the process of manufacture of sponge iron, coal injection plays a very vital role in maintaining the product quality. Due to highly endothermic nature of Boudouard reaction, heat has to be continuously supplied in entire reduction zone of rotary kiln. Generally the length of reduction zone is 60-70% of total kiln length
