Bond Impact Crushing Work Index Tester

A pendulum-type testing device used to determine the crushing work index of ores at larger particle sizes. It operates using impact crushing and helps evaluate ore competency and crusher power requirements.

Operational / Performance Insights :

• Higher impact energy produces more fines
• Product size distribution depends on applied energy
• Can simulate size distribution similar to cone crushers
• Useful for analyzing energy efficiency of crushing systems
• Helps in design of crushing circuits and equipment selection
• Can be used with drill core samples for plant design studies

• Determination of crushing work index (CWI)
• Estimation of crusher power requirements
• Laboratory comminution studies
• Evaluation of ore crushing characteristics
• Prediction of crusher performance
