clinker conveyed in the grinding stage. Their macroscopic effect is the reduction of cement coating on grinding media and mill lining and the improvement of hourly mill production and cement fineness. Using a suitable grinding aid, it is possible to manufacture more cement at higher fineness, hence reducing the kWh/t.
