• Technical Note Why is the Bond Ball Mill Grindability Test ...

    The Bond Ball Mill Grindability Test (Bond, 1952, 1961) gives the Bond Ball Mill Work Index. This Index expresses the resistance of a material to ball milling; the higher the value of the Bond Ball Mill Work Index, the more difficult it is to grind the material using a ball mill. This Index is widely used in the mineral industry for:

    Destructive Testing – Tension Test. Tension test, also known as tensile test, is associated with the mechanical test of metal products subjected to a restrained load enough to bring to the rupture. The force applied is perpendicular to the crosssectional area of the test item. Full section specimen will be tested in a 200 mm gage (8 in.) length.

  • Bond Work Index

    The ability to simulate the Bond work index test also allows examination of truned ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the .
