As well the consideration of production costs and carbon footprints, one key issue is energy consumption. For reference, the grinding process represents a significant part of a cement plant's electrical demand, in the range of 50 to 70% of the total integrated plant's needs. Therefore, limiting grinding power demand is a major industry focus.
