hydrated to hemihydrate, while there was no dehydration in the laboratory mill (45 cm X 45 cm) grinding. Study of hy- dration of the cement pastes showed that the presence of hemihydrate increased the rate of ettringite formation. Hemi- hydrate also was rehydrated to gypsum and in the process retarded the setting times.
As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO4.2H2O). Natural anhydrite (CaSO4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water.

Whether the process involves grinding, drying or calcination, the aim in every case is to eliminate water from the raw material. In state-of-the-art technology, this is accomplished using an all-in-one unit. At the end of the grinding product calcination process, the exhaust air that is produced is extracted and separated in a filter.
Dec 21, 2017 . As for the inter-grinding process, water demand is reduced by incorporation of LF and increased by reduction of R45, producing a compensation. Setting time is mainly affected by R45; LF produces a few modifications and the influence of gypsum content and gypsum–line interaction are not as.
The research work was focussed on grinding processes of beta gypsum using Pulverisette 6 planetary mill in order to obtain best technological properties. Sulphur binders originate by burnout of calcium sulphate dihydrate at different temperatures. All types are classified in air mortars therefore they can solidify, harden and.
