Khumalo et al., 2006 postulated that generally larger sized grinding media would break larger particles quicker but a finer product would be obtained by use of smaller balls. However, use of smaller grinding media is believed to support abrasion and attrition (Katubilwa et al., 2011) which are energy inefficient breakage mechanisms (King, 2001).
