Grinding Gypsum Concrete

As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum CaSO 4.2H 2 O. Natural anhydrite CaSO 4 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 inside the mill.

  • Effects Of The Clinker Gypsum Grinding Temperature Upon

    May 01, 1982 Abstract. The temperature at which Portland clinker and gypsum are ground together to produce Portland cement is shown to influence the subsequent early hydration behaviour. Raising the grinding temperature from 90 C to 130 C and thence to 170 C has resulted in increased ettringite being present at all the hydration times examined up to two hours. The results have been interpreted on the
