Minerals Free Full-Text Grinding Media Motion and ...
It is well known that the grinding media between the rotor discs undergo an axial–rotational movement: Next to the grinding disc, the grinding media are accelerated outward toward the chamber wall and flow back to the rotor shaft in the middle between the grinding discs (e.g., [1,16,20]).

Questions and answers on grinding technology - Metso
2018-10-17 This media consumes mill volume and power but the grinding is very inefficient due to the motion of the charge. All of these factors add up to inefficient use of energy. The solution to this would be to conduct ongoing calculations to ensure the optimal size of grinding media is used and to keep a close eye on media quality.
