The Cement Manufacturing Process
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they …

Recent Progress in Refuse Derived Fuel (RDF) Co-processing
This process is critical for clinker production as raw meal calcination affects the clinker quality, plant operation, and environmental emissions . A calciner is a preferred option for AF firing since it requires a low temperature (800–900 °C) for calcination compared to clinkerisation (1400–1450 °C) in the kiln.
