The high temperature causes the raw material to react and form a hard nodular material called "clinker". Clinker is cooled and ground with approximately 5 percent gypsum and other minor additives to produce Portland cement. The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs.
