The hardness of grinding balls affects their durability and performance. High-hardness grinding balls can withstand significant wear and tear, resulting in longer service life and reduced replacement costs. When selecting grinding balls, consider the hardness level required for your specific application to ensure optimal performance and longevity.
In order to determine the relative wear rates of several sizes of grinding balls, groups of 4, 3½, 3, and 2 in. balls were marked individually and were charged, all at the same time, into each of two production mills grinding copper ore. ... The indicated life of the test balls in the test mills, assuming discharge at ½ in. diam, is ...
