Calculate and Select Ball Mill Ball Size for Optimum Grinding. 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 .

Get PriceThe ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
