Testwork: Bond abrasion index - SAGMILLING.COM

2020-12-22  The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off the test coupon).
