Grinding efficiency plays an important part in calculating the work index of any Ore or Minerals. The Lab data should be precise before scaling to pilot scale and this should be repeated to come to final conclusion.Screening at 74 microns is a tedious affair and there should not be any clogging. Standard bond mill tests are the starting point.

Profile grinding is an established technology for manufacturing aircraft engine components with a high surface quality and a high dimensional accuracy, for instance, the dovetails of gas turbine blades.
