The rotary kiln is slightly inclined at an angle 2.5 degree and rotated by AC variable speed motor at a variable speed ranging from 0.2 rpm (revolutions per minute) to 1.0 rpm. Due to inclination and rotary motion of the kiln, the material travels from feed end to the discharge end of the kiln in around 7 hours to 8 hours.
The rotary kiln is a dry-type kiln allowing for heat transfer from the release of H 2 O to be neglected due to low moisture content in the raw material. Loss of mass due to CO 2 …
