Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pre-grinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old

A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and The aid also improved the dispersibility and fluidability of cement (powder) and weathering is delayed. There are various substances that can be used as a grinding aid, and

Cement is produced by co-grinding clinker, gypsum and other components defined in the Ce- ment Standards like limestone, pozzolans, fly ash and slag. The grinding is usually performed in hor- izontal ball mills. Gypsum is typically the basic source of sulphates (SO3) in the cement. The effect of gypsum on the cement
