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.
