The raw meal preparation process of the cement industry includes four links: mining, pre-homogenization, grinding, and homogenization, which form the homogenization chain of raw meal preparation. Raw meal homogenization is the most important process link of the four, accounting for 40% of the homogenization task.

In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Pre-homogenization and raw milling, and has not been discussed separately by most of the authors. However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered.
