Raw Mill Feeding. In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Prehomogenization 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.
