The Correct Option is A
Solution and Explanation
Cement clinker is produced by heating raw materials such as limestone and clay at very high temperature.
For this purpose, a rotary kiln is commonly used.
A rotary kiln is a long cylindrical furnace which is slightly inclined and slowly rotated.
The raw material enters from one end and gradually moves towards the burning zone.
During this movement, drying, calcination, and clinker formation take place.
The rotation helps in mixing and uniform heating of the material.
Roller hearth kilns are commonly used for ceramic tiles.
Shuttle kilns are intermittent kilns.
Tunnel kilns are used for many ceramic products, but cement making mainly uses rotary kilns.
Therefore, the kiln used in cement making is:
\[
\text{Rotary kiln}.
