    The performance of conventional strength enhancers can be limited by different grinding process constraints. An example is given with a process design based on a combined high-pressure-roller-press with single chamber ball mill and 3rd generation separator. It is stressed a high process sensitivity with strength enhancers.

  • Cement Milling - Understanding Cement

    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.
