Clinker grinding uses a lot of energy and the cement becomes hot - this can result in the gypsum becoming dehydrated, with potentially undesirable results - see the link at the bottom of this page for more information. Inside a (stationary!) cement mill. The part-ground clinker and steel grinding media are clearly visible.

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Laboratory-grinding mills are widely used by cement researchers and companies to assess the effect of grinding aids (GAs) on processing of clinker and energy savings. The grinding is realized either for fixed specific energy consumption (Ec) or Blaine fineness, and results compared to those of a control mix ground without GA.
