  • 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:
