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.

Fuel is combusted to produce heat for the clinker production process; coal is the traditional fuel used in China's cement industry. The raw coal from the stockyard is crushed in a hammer crusher and fed to the coal mill. The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator.
