We have asked all suppliers to maintain a higher length
of kiln when compared to their standards with a lesser
diameter which shall be of benefit in various ways, as
mentioned below:

•   Potential for higher capacity due to higher kiln volume

•   Better heat transfer due to higher retention time with

lesser RPM

•   Stable kiln operation and improved clinker quality

•   Lower velocity inside the kiln would help in reducing

kiln inlet chamber velocity to some extent

•   Complete combustion of fuel resulting in zero CO at

kiln inlet
