Clinker Production
Since then, the rotary kiln has been the main part of cement plants. It is in the rotary kiln that the basic chemical and physical reactions take place during the production of clinker. Rotary kilns are cylindrical steel tubes, slightly sloped from 2.5% to 4.5% and lined on the inside with refractory material to maintain heat.

Cement Kilns: Planetary Coolers
The coolers in practice were almost useless. Masons, using them up to the 1960s, recorded clinker outlet temperature around 1000°C, and the "quenching" of the clinker, necessary for good quality, was delayed until it fell out onto the conveyor.. A modest improvement in performance could be obtained by fitting a "van der Werp" cooler. This involved …

Process of Clinker Formation in a Cement Rotary Kiln. As a rule, the kiln feed precalcined in the preheater and calciner still contains a certain amount of CaCO3 that will be calcined to form CaO in the kiln. When kiln feed undergoes the high temperature zone in the rotary kiln, a series of chemical and mineralogical reactions occur.

Clinker leaves the kiln at 1200°C or more. Clinker at this temperature has a heat content of 1.22 MJ/kg and must be cooled in order to: avoid wasting this heat energy; obtain clinker at a temperature suitable for grinding - less than 100°C; rapidly cool ("quench") - the clinker, thus preserving reactive metastable high-temperature minerals in ...
