Abstract：The progress in new grinding technology used in modern cement industry to realize high-efficient energy saving was reviewed from the aspects of the grinding system and equipment of high-efficient energy conservation, usage of high performance grinding aids and selection of efficient grinding technology. It is suggested that the optimization of existing grinding system (such as adding pre-grinding or fine crushing, changing open system to closed system, selecting high efficiency separator etc.), selection of new cement equipment (such as rolling mill, vertical mill and roller mill) and combined system with different grinding equipment, rational use of high performance grinding aids and the choice of the most suitable grinding technology from technical and economic angles are the key techniques of energy saving and consumption reducing in nowadays cement industry, which can achieved significant economic and social benefit.
