Abstract
This guideline aims to provide tools for practitioners to measure the energy efficiency of comminution circuits using standardized metrics. Additionally, it details methods to survey and sample grinding circuits to generate sufficient information of suitable quality to support reliable efficiency analysis by these and comparable methods.
This guideline is specific to surveying and sampling of autogeneous grinding (AG), semi-autogeneous grinding (SAG), and rod and ball mill circuits operating within the normal range of application. This guideline does not directly address analysis of crushing plants and fine grinding circuits, but it is a useful reference for such endeavours.
