abstract quotIn this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material.
Of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change media size or mill speed. a general rule of thumb for mill scale
