  • Why is the Bond Ball Mill Grindability Test done the way

    The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required for grinding and for ball mill scale-up.
