Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized pebbles and ore particles. May be used where product contamination by iron from steel balls must be avoided.
