2011-1-25 · One reference and six cements were prepared by interground 0.015% of each grinding aid with gypsum and a Portland cement clinker (95% clinker, 5% gypsum). The characterization of the grinding aids was carried out by Fourier transform infra-red spectroscopy (FT-IR) and gas chromatography/mass spectrometry (GC/MS).

Optimization of continuous ball mills used for finish

During the last decade, semi-finish-grinding plants have been used more and more for the energy efficient grinding of high-quality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly.

The mill discharge had a fineness of about 1800 cm 2 /g and the material which enters the second compartment had only a fineness of about 800 cm 2 /g. Whereas the material which enters the ball mill in a Combi-grinding plant is much finer (∼2000 cm 2 /g). Therefore, this results can’t be transferred directly to the one compartment ball mills in Combi-grinding
