Grinding was performed in the absence of reagents, at 67% solids using respectively; ceramic balls, forged steel balls, 15% Cr steel balls, stainless steel balls and ixture of stainless steel and 15% Cr steel ballsa 50:50 m .

Wear of grinding media in the mineral processing

Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding (SAG), rod milling, and conventional ball milling. Each of these mill environments presents a unique environment for grinding media, requiring the application of specific physical and chemical properties for optimum grinding media performance.

Effect of agitator shaft direction on grinding

Furthermore, the grinding media in the low sections actively mixed with the grinding media in the upper sections, thereby resulting in a more uniform energy transfer and in a better grinding process. Accordingly, this study demonstrated that not only the collision energy but also the uniformity of the movement of the medium particles should be

Effect of Grinding Media Shapes on Breakage

In the present study, the effect of grinding media shape on breakage parameters was investigated. Balls and cylpebs were used as the grinding media. It was observed that the grinding of quartz obeyed first‐order breakage kinetics in the case of balls and cylpebs. Higher breakage rates were noted with cylpebs than with balls. Furthermore, it was found that the primary breakage distribution
