Using Abrasion Index for calculating Steel Balls and …
I know of a practice that uses 50 percent of the theoretical consumption calculated by the Bond formula for ball mills; for SAG Mills 65 percent of the theoretical consumption is used considering the SAG mill as a ball mill.The rotating paddle used in the Bond Ai test is made of SAE4325 steel hardened to 500 Brinell and therefore not necessarily equal to the hardness and abrasion resistance of ...
