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.

In cement plants increased airflow through the cooler reduces secondary air temperature, and therefore, the flame temperature, thus requiring even more fuel to heat the charge to the required process temperature and the increase in fuel consumption is much greater than that needed just to heat the excess air to backend temperature.

In the absence of preblend / storage of limestone and shale, or if the materials as fed to the raw mill are effectively dry, silos are appropriate for the feed materials. Where wet materials are fed for drying in the raw mill, silos are unnecessary. Ball mill operation is described in more detail under finish milling (Section ).

Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.
