    In order to provide consistent ore grindability and hence maximize output, it would be desirable to blend these types of ore into one uniform mixture for feeding to the mill lines. Although the three types could be blended by building up successive layers on a stockpile so that, when reclaimed, a more or less uniform mixture is formed, it would be more satisfactory to store the three types in ...

  • Measurement of impact breakage properties of ore

    Single particle impact breakage experiments provide essential data to aid in the fundamental understanding of rock fracture in comminution. Such experiments, conducted using devices such as the drop weight tester, split Hopkinson bars and more recently the rotary breakage tester, have been successfully used to characterize ore breakage properties in relation to measured fracture energies.

    Breakage rates were higher for steel ones comparing to ceramic balls. Furthermore, it was found that the primary breakage distribution function depends on the feed size (i.e., non-normalized), and depends on the different grinding media. The effect of grinding time on the product particle size distribution has also been investigated.
