size of grinding ball is 25 mm or bigger. As mentionned by various authors (Jankovic, Valery and La Rosa, 2003; Gao and Holmes, 2007), conventional ball milling was discarded because of its very poor energy ef fi ciency caused by those larger balls. Therefore, new technologies as stirred mills were developed to grind fi ner more effi ciently.
