How Cement Is Made in Rotary Kiln | Rotary Kiln Manufacturer
However, it does require the meal to be pre-heated. So, the pre-cement starts in a large tower, going through a multi-stage heating process until it's already at around 900 C. This helps convert the limestone into calcium before it even reaches the kiln. Once the heated dry meal enters the rotary kiln, it is rotated as it moves downhill ...

Everything you need to know about Kiln Burning Systems
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.
Cement Kilns: Design features of rotary kilns
The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to …
