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.

Grinding and homogenization
Grinding and homogenization. The grinding process takes place in a raw mill to reduce the particle size of the components to a typical value of 10-15 % residue on a 90 um sieve. The output of the grinding process – called 'raw meal' – is transferred to a homogenization silo before the clinker manufacturing process.
