·In the conventional process of cement manufacture high temperatures are maintained by rotary furnace around 1450 °C for 60 min to obtain the clinker however the clinker process through microwave furnace needs lower temperature Fang et al 1996 Microwave heating is a process of microwave material interaction
The cyclone preheating system Phase IV Calcination The calcination is the core phase of the cement making dry process The calcination of the preheated raw meal takes place in the rotary kiln of the cement plant The rotary kiln is a huge rotating furnace in which the raw meal is heated up to 1450 ⁰C and turned to clinker
·The cement manufacturing process mainly includes four steps resource extraction raw material preparation clinker calcination cement grinding 17 18 and fossil fuel burning 19
The cement kiln is a vital component of the cement manufacturing process playing a critical role in the production of high quality clinker Advances in kiln technology have significantly improved energy efficiency reduced emissions and enhanced the overall sustainability of
The overall process of conversion from raw meal to clinker being endothermic demands a theoretical heat of about 380 420 kcal/kg clinker However the rest of the specific heat consumption as tabulated above constitutes heat losses from preheater exhaust gases clinker cooler exhaust gases preheater dust and radiation losses
·The use of cement and concrete among the most widely used man made materials is under scrutiny Owing to their large scale use production of cement and concrete results in substantial emission
Clinker reactions in the kiln However reading an article or two is perhaps not the best way to get a clear picture of a complex process like cement production To get a more complete and integrated understanding of how cement is made do have a look at the Understanding Cement book or ebook This easy to read and concise book also
