**Bond Work Index an overview ScienceDirect TopicsBond impact crushability work index (CWi) (Bond, 1963) results reported for iron ores vary from hard iron ore (17.7 kWh/t) to medium hardness iron ore (11.3 kWh/t) and friable iron ore (6.3 kWh/t) (Table 2.11Clout et al., 2007). Bond Impact Crushing Work Index Procedure and Table of Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper.
