Homogenization (BLENDING) - Cement Plant Optimization. Homogenization (BLENDING) In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality.

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.
