How Cement Is Made in Rotary Kiln | Rotary Kiln …
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 ...

Cement Kilns: Design features of rotary kilns
The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load.
