  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    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”.

  • How Coarse can Ball Mill Feed be Grinding

    A quick check of the Rowland optimum feed size for this ball mill is between 3 and 4 mm; operating either circuit you describe will be at least 15% inefficient compared a more conventional ball mill feed size.

  • Optimum choice of the make-up ball sizes for maximum

    For the feed size of 90% passing 18.9 mm (Fig. 6a), the maximum capacity was obtained with 100% of a make-up ball size of 50.8 mm. As the feed size is reduced to 13.4 mm, a 62:38 mix of 50.8 mm and 25.4 mm balls was found to be the optimum mix.
