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. add to this another 10%-15% above the ball charge for total of 23%

the starting point for ball mill media and liquid charging is generally 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. add to this another 45% to 50% above the ball charge for total of 58%
