This guideline describes the Bond method for quantifying and comparing the relative energy efficiency of most industrial comminution circuits.
The objective of this guideline is to provide a benchmark metric for the specific energy requirements of an industrial grinding circuit, in comparison with a standard circuit designed with a set of standardized laboratory tests. Additionally, the actual plant circuit and can deploy any type of size reduction equipment, allowing this tool to be used by operators and designers to benchmark the energy efficiency of any size reduction circuit, over the applicable size reduction range, that exists in the industry. Examples of calculation of the Actual Operating Bond Work Index (WioACT) and Wi Efficiency Ratio for different industrial circuits are provided.
This document also intends to provide guidelines to standardize Bond test equipment and procedures to minimize the testing experimental error, minimizing plant Bond Efficiency measurement error and maximize the usefulness of this efficiency value for performance benchmarking and process improvement.
The guideline provides further explanation on:
