Since the 1900s, rotary kilns replaced the original vertical shaft kilns, as they use radiative heat transfer, more efficient at higher temperatures. achieving a uniform clinkering temperature and produces stronger cement. Gypsum is now also added to the resulting mixture to control setting and ball mills are used to grind clinker.

The variation is due to the energy requirement for the evaporation and, hence, the moisture content of the raw meal. Originally, the wet process was preferred because it was easier to grind and control the size distribution of the particles in a slurry form. The need for the wet process was reduced by the development of improved grinding processes.
