The basis is a 40 mm ball size for 5% residue on the 2 mm sieve. In case bigger grains are bypassing the partition through the center grate, even 60mm balls can be considered. Raw mill: The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall.
