Question

During cement manufacturing, when clinkers are formed, kiln temperature approximately is

• A. ${1200}^{o}C$
• B. ${1800}^{o}C$
  
• C. ${1600}^{o}C$
• D. ${1300}^{o}C$

Answer 1

The correct option is C ${1600}^{o}C$

Burning of Clinker is done in rotary kiln. The temperature at lower end is 1400-1500° C, while it is less at the upper end. In this zone argillaceous and calcareous materials combine chemically to form cement compounds $C_{3}S,C_{2}S,C_{4}AFand{C}_{3}A$.
