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.

The recent history of the technology has been mainly concerned with reducing the energy consumption of the grinding process. Materials ground Portland clinker is the main constituent of most cements. In Portland cement, a little calcium sulfate (typically 3-10%) is added in order to retard the hydration of tricalcium aluminate.

and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.

Blended cements can be produced in two ways: by intergrinding the components or by separate grinding and mixing them. With the intergrinding process all components of the blended cement are ground together. In that way the cement is homogenized during the grinding, and at the concrete plant only one silo is needed.

The mill is operated on a barter system of the miller collecting a toll for payment of grinding grain. The mill does batch grinding for farmers and local individuals on a first come, first serve basis. The mill does not clean up in between each batch of grinding grain.
