    A discussion on the measurement of grinding media wear,

    The consumption of the grinding media represents an expressive part of the grinding operational costs; it may reach up to 40% of the costs in a mineral processing unit , and wear constitutes around 60% of the cost relative to ball mills .TYPES OF GRINDING MEDIA - energosteel,Types Of Grinding Media.,As shown recent researches, the ball charged to the ball mill has a large contact area, providing better quality of grinding in comparison with the grinding cylpebs. In confirmation of this, currently, almost all the companies partially or completely refused of using cylpebs during grinding.Evaluation of commercial US grinding balls by laboratory,,simulating the grinding of ore between balls in a ball mill (Diesburg and Borik, 1975; Gundlach and Parks, 1978). Corrosion can account for a third cause of ball degradation when grinding ore wet. In laboratory tests under very acidic conditions of pH 2, we found that corrosion and abrasion combined to aggravate wear (Tylczak, et al., 1986).
