Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits significantly, the [.]

with wellknown international cement companies such as Holcim, Heidelberg, Lafarge, Cemex, Buzzi Unicem and many others. In the 1970s, Vertical Roller Mills (VRMs) became increasingly dominant for grinding raw materials, mainly for the cement and power industries, due to their high energy efficiency and excellent drying capacity.

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
