For that purpose, there has been observed the grinding kinetics of narrow size fractions of quartz and copper ore sizes (-080/+063 mm; -063/+050 mm; -050/+040 mm and -040/+0315 mm) with the ball charge of different diameters (Table 1) The dry mill grinding has been conducted

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space

Ball Size as Initial Charge Commercial ball sizes 10 – 150 mm; 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
