What is the main function of rotary kilin:
Correct answer: D. Preparation of clinker
- A. Heating lime stone
- B. Heating of clinker
- C. Drying of slurry
- D. Preparation of clinker
Explanation
Rotary kilns are primarily used for the preparation of clinker, which is a key intermediate product in the production of cement. During the process, raw materials such as limestone, clay, and other minerals are heated in a rotary kiln to high temperatures, typically around 1450°C, to produce clinker. The clinker is then ground to produce cement.
