Parametric Studies of Cement Production Processes
The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO<sub>2</sub> emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity. The ...

Cement - Wikipedia
The high pH prevailing in the cement porewater12.5 < pH < 13.5limits the mobility of many heavy metals by decreasing their solubility and increasing their sorption onto the cement mineral phases. Nickel , zinc and lead are commonly found in cement in non-negligible concentrations.

Effects of grinding aid dosage on circuit performance and ...
In order to investigate the effects of GA on cement grinding circuit, three different dosages of a commercial GA were tested and samples were collected around the circuit. The GA used during the tests was amine-basedmajor active material was triethanolamineand has a specific gravity of 1.033 g/cm 3 and a pH of 10.73.

Industrial versus Laboratory Clinker Processing Using ...
The evaluation of grinding aidGAeffect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed-circuit tube mill operating at ...
