    The aim was to study ball size variations throughout the cycles. Traditionally, mill media wear rate is evaluated by measuring the media level in the mill, or by removing media charge and weighing it after a certain number of hours. As mentioned above, the mill was stopped after 24 h (one cycle) with a total of 24 cycles for each ceramic ball type.
