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. For stable kiln operation and to obtain uniform quality of clinker it is necessary to keep the variation in kiln feed in LSF 0.5, in SM 0.03 and in AM
