cement hydration improving strength development [1]. In this paper we present a typical example of full investigation about the possibility of producing high early strength type I cement, using an appropriate cement additive. We were approached by a grinding plant with the target to produce a Portland cement (CEM I
The study shows that the cement grinding plant has various dust sources that cement workers potentially expose daily. The TSP concentration in this study was in the range of 0.15 and 25.62 mg m −3. The results of the TSP measurement reveal that four out of six processes in the cement grinding plant exceeded the PEL for an 8-h working shift.
The PSD of cement and/or its components has an important influence on water demand, the setting behavior, and the strength development of cement in mortar and concrete. The PSD of the product depends significantly on the mill system used for cement grinding and therefore especially affects the choice of cement mills.

For raw grinding with relatively dry raw materials, the combination of the roller press and V separator is a viable alternative with far lower mill fan power. Cement grinding For cement grinding, the technology development away from ball mills has taken a different route.
What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.
