OCCUPATIONAL HEALTH AND SAFETY IN CEMENT INDUSTRY
The most commonly used kiln fuels are coal, natural gas, and occasionally oil (EPA 1994). Rotary kiln is heated by a 2000°C flame inside of it. The kiln is slightly inclined to allow for the materials to slowly reach the other end, where it is quickly cooled to 100-200°C (CEMBUREAU).
