Jun 01, this approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is optimized. the same policy is employed for the make-up charge where adding different ball.
Mill Steel Charge Volume Calculation
Jun 19, we can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. while the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. the % loading or change volume can then be read off the graph below or approximated from the equation and calculation: % steel charge loading in mill.

Ball Mill Loading
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%.
