Kiln Feeding
The main objective of a kiln feed system is to feed the kiln at any desired rate set by operator (from CCR) and to maintain it with a close degree accuracy (± 2 %) throughout the feed rate range. A fraction (5-12%) of kiln feed gets lost with preheater exhaust gas. As the chemistry of this dust is normally different from kiln feed composition ...

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 ...
