In terms of energy, grinding process efficiency could be enhanced by using the VRM, and cement plants could conserve a considerable amount of their energy by exploiting VRM [13]. Literature showed that using VRM instead of a ball mill could reduce Zinc grinding power consumption from to kWh/t of raw materials (kWh/1000 kg) [14].
