With its excellent potential for resisting wear the matter of toughness became, crucial. Its performance in grinding mills would depend on whether it chipped, thus adding a second deterioration mechanism to that of abrasive wear, and on whether there would be gross breakage under mill impact conditions.
Key words: grinding media; wear rate; ball mill abrasion test. 1. Introduction Grinding media should be produced to provide the greatest performance that is the lowest wear rate and highest grinding transfer to cost ratio. Ball producers utilise different manufacturing methods, based on the properties, size and chemical composition of the product.
