Grinding: The clinkers which are output from the rotary kiln are very hot hence they are first cooled by air in a countercurrent fashion. The clinkers are of size of about 5-10 mm. They are fed to grinders in order to grind them to reduce their sizes. The clinkers are fed into ball mill or tube mill along with powdered gypsum.

In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln. The dry process is much more thermally efficient than the wet process.
