The first rotary kiln was introduced to the cement industry by Frederik Ransome (1885) when he took out a patent in England titled "Improvements in Manufacture of Cement." The first of these rotary kilns were up to 2.0 m in diameter and 25 m long, with an "enormous" production of 30 to 50 ton/day.
It is no secret that infrared technology has been widely embraced by the cement industry for more than 20 years; while all infrared rotary kiln systems offer the basic capabilities highlighted above, newer systems developed in the last decade feature some of the latest technology in the industry and offer expanded functionality to support operator needs.
Each kiln subsystem (including the preheater and clinker cooler) has an important bearing on the time and temperature required for passage through the sintering zone to get clinker that will produce high quality …
Instead of granulating the kiln feed, some plants use filter press cakes to feed the kiln. In such cases, the wet-kiln feed slurry is first passed through large presses for removal of the free water and more importantly, to remove alkalies before the filter cakes are fed to the kiln. ... Heating of the nodules is effected by the exit gases from ...

In the 20th century, the vertical kiln in most developed countries is gradually replaced by a type of more advanced and environment-friendly cement kiln, the rotary kiln.
— How this would fit with any kiln electrification plans is unknown. However, one attraction of moving to an electrical kiln, for all of the projects above, is to cut out the 40 – 50% of a cement plant's CO 2 emissions that arise from the fuel that is burnt. Taking a kiln electric also makes CO 2 capture easier.
