• Accurate Scale Up

    In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill. Additionally while techniques like the Bond Work Index and "scale up factors" are useful for coarse grinding, they can significantly ...
