The most common abrasion test however, is the Bond method where a 76x25x6mm (3x1x0.25″) piece of 500 Brinell SAE 4325 chrome-nickel-molybdenum steel rotates in a falling stream of rocks under standard predetermined conditions to measure its weight loss. The resulting Ai is used to predict crusher liner wear rates.
