    The size of grinding media plays a key role in overall performance of the grinding circuit. Larger grinding media has a smaller grinding surface area, but offers a heavier weight that’s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller.3 SURFACE PROPERTIES OF GRINDING MEDIA Grinding media selection is usually focused around the parameters listed in 1.1. In testing of MT1 during product development, it was found that grinding efficiency was greater than other media types of similar size, shape factors and SG. In fact, grinding efficiency was better than could.

    Steel grinding media fail if there is a significant variation in chemical composition, hardness and microstructure of the balls. Common failure modes of grinding balls observed in different semi autogenous grinding (SAG) applications are misshapen surface spalling, shelling, capping and half balls5. This paper discusses the main quality.The area of grinding contact between the wheel and the work affects the choice of grift size and grade. A coarse grift is required when the contact area is relatively large, as in surface grinding with cup wheels, cylinders or segments, to provide adequate chip clearance between the abrasive grains.

    The specific surface area (SSA) of the calcite sample before grinding was 0,23 m2 g. The grinding media selected for the tests was 3.5 4.0 mm alumina (Al 2 O 3) beads (Table 2). The physical properties of grinding media are presented in Table 3.Mill, cylindrical shaped grinding media produces faster breakage rates than ball charges under the same conditions 6. According to Ipek et al.7, it might be explained due to the contact mechanism and the higher surface area of the cylindrical media. On the other hand, Kelsall et al. 8 found that cylinder and cubes always produce fewer fines than.
