Quantifying Grinding Efficiency

Grinding efficiency could be defined in many ways, useful consumption of energy usually being the parameter to be maximized. The Bond Work Index is a measure of theoretical power consumption to grind to a certain size while the Operating Work Index can be measured for an industrial system and reductions in Operating Work Index show improvements in efficiency.
