THE PRODUCTION PROCESS OF CEMENT

Production Process of Cement

chalk & clay  + water ------> slurry or dried powder

 the slurry or dried powder will undergo wet process or dry process

WET PROCESS

1.) Slurry fed into higher end of inclined rotary kiln.

2.) Heated as mixture passes down the kiln under combination of action of rotation and gravity.

3.) Mixture under increasing temperature as it passes down the kiln undergoes four physical and chemical changes.

i. Drying

ii. Preheating

iii. Calcining

iv. Clinkering

DRY PROCESS

1.) Dried powder preheated and some calcining in heat exchanges.

2.) Mixture fed into the higher end of inclined rotary kiln.

3.) Mixture undergoes two chemical changes with increasing temperature.

i. Calcining

ii. Clinkering
