A mathematical analysis of milling mechanics in a planetary ball
Abstract. A detailed mathematical analysis is presented to advance the current understanding of the mechanics of milling operation in a planetary ball mill in Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; Design, Construction and Performance Analysis of a 5
