Any cement raw material investigator needs to keep a few important points in mind starting from the fact that this industry is very capital intensive, large gestations time, varied raw materials in large quantities are handled in the plant involving different processes such as mining, crushing, grinding, pyro-processing and finished grinding ...

The grinding process involves reducing the clinker particles to a specific fineness, typically measured in terms of Blaine specific surface area or particle size distribution. The grinding process significantly influences the cement's strength development, setting time, and other performance characteristics.

Cement plants (CPs) are one of the most important anthropogenic sources of mercury (Hg) emissions in China. Over 1000 cement production lines operate in China and use various raw materials; however, little data on Hg emissions is recorded on site. This study investigated a CP in Guizhou Province that uses multiple mining and industrial …
