These pellets are then used for making sponge iron. rotary kilns have a drawback upon the size and quality of iron ore that can be used. initially, when the process was first introduced, the ore with an iron content 65 was preferred and the preferred size of ore was 5-18mm.
Since in the rotary kiln the reduction of iron ore takes place topochemically5, the rate of oxygen removal from t single iron ore particle can be expressed as of total oxygen removed froc the charge 1,ed, hence, pco pco2k, 1.-13-1.4 f-3 . o rate of carbon gasifications for temperature upto
The four horizontal rotary kilns are the heart of the reduction process. the residual char carbon remaining after the coal was heated is used to achieve the chemical reduction of iron oxide to iron. a number of chemical reactions occur in the kilns because coal and ironsand are not pure substances like laboratory chemicals.
Jun 30, 2011 the increase in the demand of sponge iron is also due to the fact that it is used as a substitute for coking coal which is available in scarcity in the world. this book comprehensively deals with the production of sponge iron in the rotary kiln. the book is divided into 17 chapters. the initial chapters give a brief on the fundamental theories and basic principles of sponge iron production ...

The first requirement is a high quality iron ore or pellet with total iron content of 64- 67. this is because all the gangue remain s in the dri and high quantities will slow
Once ore has been dried, it is processed in a large-scale rotary kiln to remove chemically bound moisture, as well as the oxide component of the ore. this step is often referred to as pre-reduction. reduction amp smelting. nickel is further reduced and smelted in an electric furnace.
Jan 01, 2015 the ratio in the output from the three main pelletizing technologies changes depending on practical circumstances, such as iron ore reserves, iron ore types, market demand, and required investment. the ratio for grate-kiln pellets has increased to 55.33 in 2011 from 7.21 in 2000, while the ratio for shaft furnace pellets has dropped to 42.05 ...
