In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al .[ 19 , 20 ] found a scale-up factor for the Isamill of exactly 1, while Gao et al .[ 8 ] imply that the scale-up factor for SMDs is 1.25.

Many impact mills and hammer mills and most ball mills can be set to produce ground ore of any size from -20 mesh to -200 mesh. The impact mill does this by recycling the larger pieces back through the mill. This process in itself causes extra wear, because the pieces that do not break up are extra hard and extra abrasive.
