The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran 1978 to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company

Aug 01 2018 Coal ash particles together with disintegrated iron-ore pellet dust particles accumulate on the refractory walls resulting in the build-up of scaffold deposits most drastically in the hot areas e.g. fireside slagging closer to the burner transfer chute inside the rotary kiln and the beginning of the cooler . Consequently the build-up of these sintered deposits disturbs the flow of gas and pellets and
The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in pre-determined ratio. The rotary kiln is slightly inclined at an angle 2.5 deg and rotated by ac variable speed motor at a steeples variable speed ranging form 0.2-1.0 rpm.
Nov 13 2020 In coal-based DRI plants rotary kiln is used for the reduction of iron ore. Accretion rings formations inside the kiln adversely affect the performance of plant in terms of low production and inferior quality which frequently lead to shut down. About 70 of the coal-based DRI rotatory kiln shut down is due to the accretion formation .
rotary kilns and increases the reduction rate and productivity. The process is also characterized by flexibility regarding various raw materials including iron ore fines steel mill waste and non-coking coal. This paper outlines the features and development status of Kobe Steels coal-based reduction processes
It has now been discovered that the haematite iron ore fines can be fed directly to the rotary kiln without previous agglomeration that the iron content of the reduced ore product as discharged from the kiln can be easily separated and beneficiated and that the sponge iron concentrate obtained from the beneficiation can be rolled without the use of substantial mechanical pressure into pellets which are
Mar 16 2013 In the rotary kiln both coal and the iron ore feed material is charged from the same end of the kiln. During the movement of feed material forward the oxidation reaction of carbon in coal and reduction reaction of CO gas is carefully balanced. A temperature profile ranging from 800 deg C to 1050 deg C is maintained along the length of the kiln .
