in grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do. often, the ball used in ball mills is oversize “just in case”. well, this safety factor can cost you much in recovery and/or mill liner wear and
the milling cutter bodies can also be one-side fitted for milling of one surface. feed per tooth, or mid hm chip thickness, which should be between 0.004" to 0.008" for fixed and 0.003" to 0.004" for adjustable disc milling cutters, is also an important parameter when selecting cutting conditions.
