Grinding of clinker consumes power in the range of 2.5 kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and …

The valorisation of cement kiln bypass dust (CBPD) is explored for sustainable production of cementitious clinker phases. CBPD can replace the calcareous component in cement manufacture and allow for a reduction in CO 2 emissions, as the calcium component in CBPD is mostly decarbonised. CBPD was heated with/out the …

In the kiln stage, the principal stage of cement making process, clinker is produced from the raw mix fed to the kiln through a series of chemical reactions. This process of clinker formation in the kiln at high temperature is known as pyroprocessing. After exiting the kiln, the clinker is rapidly cooled down from 2000°C to 100°C-200°C by ...
