The manufacturing process of cement is a highly electrical energy intensive process. Size reduction in a plant consumes 55-65 % of the total electrical energy consumption accounting for 30-40 % of the total production costs. So, a ball mill used for cement production consumes nearly 30-35 % of total power consumption of the plant.
