Cement milling: The clinker is ground by different-sized steel balls while it works its way through the mill’s two chambers, with gypsum being added to extend cement setting times. Cement packaging and shipping : The cement is then housed in storage silos, from where it is hydraulically or mechanically extracted and transported to facilities where it will be packaged in sacks or supplied in

The milling process in cement plants is extremely energy-intensive. there are potential energy savings available through the use of Mill Control System (MCS). The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledge-based approach using current plant data (defined measured values).
