Q: To obtain cement dry powder, lime stones and shales or their slurry, is burnt in a rotary kiln at a temperature between
  • A. 1100⁰ and 1200⁰
  • B. 1200⁰ and 1300⁰
  • C. 1300⁰ and 1400⁰
  • D. 1400⁰ and 1500⁰
Correct Answer: Option D - The slurry cones out as a clinker though the three chamber left from the upper and of the rotary furnace. (1) Drying chamber – in temperature varies 250-500⁰C and their dry slurry. (2) Calcinations chamber– There is slurry calcination, temperature here is 700-1200⁰C and slurry is burnt and prepare. (3) Clinker chamber – It is the lowest and warmest area, and the temperature varies 1400-1700⁰C. In this chamber take chemically activities.
