The cement kiln burns rawmix to produce clinker, which is then ground to make cement.. The cement kiln is the heart of the cement making process: this is today almost a cliché, but was not always quite so true. In the modern cement plant, the kiln is the most expensive and technically complex part of the plant, and because it must be run all the time (unlike other sections of the …

5. Clinker Formation in the Kiln (Pyroprocessing) The rotary kiln is where the most critical transformations take place. The kiln heats the materials to 1400-1500°C. Calcination occurs, where limestone (CaCO₃) decomposes into lime (CaO) and CO₂. This forms clinker, small grayish-black nodules, which are the main component of cement.
