• Effect of chemical composition of clinker on grinding

    About 30 of the energy required to produce one ton of cement is consumed in grinding. It is a significant percentage of the total cost of cement. The energy consumption in the cement mills varies between 16.5 to 63.5 kWh/ton with an average of 36kWh/ton . There are numerous factors affecting the energy consumption during clinker grinding.
