    The energy efficiency of ball milling in comminution ...

    where E m (SP) is the specific energy required to produce a product of a given median size X 50 by single particle comminution and E m (Mill) is the specific energy to produce the same median size in a comminution machine, such as a ball mill. This means that the energy efficiency of a comminution device can be assessed as to how closely the performance of the device approaches single particle

    For tumbling mills the specific comminution energy (Wi) relates to the power at the pinion or for gearless drives the motor output. For HPGRs it is the energy inputted to the rolls, whilst for conventional crushers Wi relates to the specific energy as determined using the motor input power less the no load power.
