Grinding aids are added at low dosages, typically in the range of 0.02 - 0.05%, to the mill feed or directly into the mill itself. Grinding aids reduce or even neutralize the surface energy by shielding the polarity to different degrees. Therefore, the particles do not attract each other anymore and the production process is optimized.

Grinding aids work mainly by dispersing ground cement particles to avoid agglomerates, enabling an increase in production of up to 25 per cent. In vertical roller mills, they can additionally be used to reduce vibrations and the amount of water injection, and thereby improve cement quality.
