CHAPTER 3- MECHANICS OF GRINDING

The main reason for abnormality high wear rate of grinding wheel as compared to edged tools (the ratio is about million times) is due to weaker bond of the wheel. Test on single grain cutting (i.e. by fixing a single grain on the surface of the disc wheel) have shown some startling results. A single grain of aluminum oxide has the capability

List Factors Affecting Grinding Ball / Media Wear Rate

a) In high wear rate applications like SAG and primary grinding, the high Cr ball has 0 – 30% lower wear. b) In low wear rate applications, the high Cr relative performance will depend on the corrosivity and abrasivity of the environment. In high corrosivity environments, the high Cr balls can have less than half the wear of forged steel.
