ball charge formula in cement mill
THE OPTIMAL BALL DIAMETER IN A MILL
then the determination of the optimal ball charge model in a mill. 2. Theoretical background Each grain size corresponds to a definite optimal ball size. The diameter of a ball is determined by the condition that, at the moment of breaking the grain, it has energy E, which is equal to energy E 0 necessary for grain comminution:

Ball Mill Loading - Dry Milling - Paul O. Abbe
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% ...
