Clinkering is the primary step in the cement manufacturing process. The function of the kiln in the cement industry is to first convert limestone into lime, then react it with silica, aluminum oxide, and ferric oxide to form clinker compounds: C 3 S, C 2 S, C 3 A, and C 4 AF. The kiln is the heart of this production process.

Raw Mill Feeding. 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.
