Bond Work Index an overview ScienceDirect Topics
The most widely used parameter to measure ore hardness is the Bond work index Wi. Calculations involving Bond’s work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (Wi C, CWi or IWi (impact work index)).
