limestone grinding energy

Energy-Efficient Technologies in Cement Grinding

They are used in grinding of cement raw materials (raw meal) (i.e. limestone, clay, iron ore), cement clinker and cement additive materials (i.e. limestone, slag, pozzolan) and coal. Multi-compartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t).

Aug 12, 2014  The limestone is more easily ground than the clinker, which is harder, and becomes concentrated in the finest particles. Overall fineness must be higher (for equivalent performance) for fineness of the clinker fraction to be similar to OPC. This means the production rate is slowed and some additional grinding energy is required.
