Production Process | CEMEX Philippines

In this process the limestone and clay are first pre-homogenized, a process that consists of combining different types of limestone and clay. The resulting mix is typically dried, and then prepared for the kiln. In the kiln, the raw materials are processed at a very high temperature to produce clinker.

Chemicl parameters defining clinker composition

If the LSF is higher than 1.0, the surplus free lime has nothing with which to combine and will remain as free lime. In practice, the mixing of raw materials is never perfect and there are always regions within the clinker where the LSF is locally a little above, or a little below, the target for the clinker as a whole.
