    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.

  • A discussion on the measurement of grinding media wear

    Laboratory mill tests can be an alternative to assess the wear of grinding media, as they can reproduce, at least partially, the conditions of an industrial ball mill. Moreover, they are less expensive and less time-consuming than the tests performed at industrial mills. Furthermore, it may contribute to the development of materials for grinding media, as well as offering users an efficient
