Cement grinding Vertical roller mills versus ball mills
The consumption of grinding aid when grinding OPC in a vertical roller mill is typically in the range from 100 g to 300 g per ton of cement. With respect to the use of grinding aid for grinding of OPC, the ball mill system thus has an advantage compared to the vertical roller mill.

Improving cement grinding | GCP Applied Technologies
The majority of CO 2 produced during cement manufacture arises during clinker production, due to the calcination of calcium carbonate, fossil fuel burning and electricity consumption (mostly for grinding). Using a base CO 2 factor of 862kg CO 2 /t clinker, each one percent drop in clinker in cement can reduce emitted CO 2 by 89kg/t cement.
