Abstract
A source of free lime is introduced into a cooling zone of a cement kiln in an amount to elevate the free lime content to a content of 0.6 to 2.0%, by weight. This addition is made without altering the normal or standard process operating parameters of the kiln for cement clinker production. The free lime content of 0.6 to 2.0%, by weight, provides advantageous characteristics in cement produced with the cement clinker.
