A.A boateng, in rotary kilns second edition, 2016.10.4 the cement-making process.Rotary kilns are synonymous with cement making, being the workhorses of this industry.There are many types of rotary kiln arrangements for producing cement clinker with each incremental design goal aimed at improving energy efficiency, ease of operation, and product quality and minimizing environmental.
A.A boateng, in rotary kilns second edition, 2016.1.1 the rotary kiln evolution.Rotary kilns have been synonymous with cement and lime kilns probably because of the history of their evolution and development.It has been reported that cement deposits characterized by israeli geologists in the 1960s and the 1970s place cement making at 12,000,000 bc when reactions between limestone and oil.
Rotary kilns sometimes called calciners or rotary furnaces are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
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.
