Clinker

Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions).

The clinker manufacturing process

The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality. The preheating of the material takes place in pre-heater cyclones fitted with a pre-calciner fired with petroleum, natural gas or coal.
