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).

Commentary on the apparatus of the Bond rod mill work
• The nature of the breakage will be skewed toward abrasion breakage in the smooth liner designs, whereas the wave liner will have more attrition (and possibly crushing) breakage. The first problem comes from the equation derived by Bond to calibrate a rod mill work index to the parameters of the rod mill tumbling test.
