EnergyEfficient Technologies in Cement Grinding | IntechOpen
· They are used in grinding of cement raw materials (raw meal) ( limestone, clay, iron ore), cement clinker and cement additive materials ( limestone, slag, pozzolan) and coal. Multicompartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t). Typical specific energy consumption is 30 kWh/t in grinding of .
