    Modified Bond Ball Mill Work Index TestWhat is this

    The Thirty-nine samples were submitted for the Crusher Index (Ci) SAG Power Index (SPI®) Standard Bond Ball Mill Work Index (BWI) and Modified Bond Ball Mill work Index (MBI) tests. The Ci SPI® and Bond Wi values of these samples show a good indication of ore hardness variability within the ore body.
