An innovative approach for determining the grinding

2021-1-22 · The grinding experiment was operated with the Anshan type iron ore. The results of the laboratory grinding experiment indicated that the media size ratio, space-filling factor, and material ball ratio had a significant influence on the grinding kinetics of the iron ore sample. (2) The average grinding rate increased with a decrease in media size.
