This guideline condenses the works of the Morrell method for predicting the specific energy consumption of conventional crushing, High Pressure Grinding Rolls (HGPRs) and tumbling mill equipment and applies them to assessing operating comminution circuit performance. Such circuits include combinations of any of the following...

This guideline is for measuring comminution efficiency in global mine operations using the Bond method and comprehensive Bond Work Index. This method allows personnel to quantify and compare relative energy efficiencies and offers a mode of benchmarking to observe energy consumption. It is an essential...
