3.4 Burning in a kiln – formation of cement clinker

3.4 Burning in a kiln – formation of cement clinker. The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw mix.
