Mill discharge product sie in relation to the lifting effect of the liners. In this specific case it is obvious that a certain load expansion is needed to allow the coarse particles entering the media charge to be reduced. Therefore at this stage a direct measurement of the dynamics in the mill gives very valuable information to the operator.
