  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    Feb 7, 2018 In his paper "The Preferred Size of Balls for Ball Mills." Mr. V. A. Olovskiy concludes: The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target P90 . Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log

    It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding
