Cement grinding a comparison between vertical roller

The consumption of grinding aid when grinding OPC in a vertical roller mill is typically in the range from100 to 300 g per tonne of cement. The ball mill system thus has an advan- tage compared to the vertical roller mill with respect to the use of a grinding aid for grinding of OPC.

Ball Mills Or Vertical Roller Mills: Which Is Better For

Operating a ball mill is quite simple as it lacks any moving mechanical parts within the mill. The system is quite versatile and is designed to accommodate variation in mill feed quantity and quality. On the other hand, the vertical roller mills (VRM) is quite a complicated and sophisticated equipment with hydraulics that controls the rollers.
