Actual inhalable dust concentrations depended to a large extent on specific conditions ...

calcareous raw material) and clay, mudstone or shale as the source of most of the silica and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement.

The dust generated during grinding has the potential to be dangerous, from creating a slipping hazard to possibly contributing to a combustible metal dust fire and explosion. To avoid the latter, metal fabricators should look at equipment that is designed to keep a dust-related catastrophe from occurring. Getty Images.
