AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill ,

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, ie, d↓V = 040 K√F dB = ball size (cm) F = feed size ,
