Home/matching ball mill drum size to charge volume
Mill Steel Charge Volume Calculation. 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

For fresh charge, it is the most general practice to use three different ball sizes: 25% of large size, 50% medium size & 25% small size. There might be cases where using 2 to 4 different sizes of grinding balls may be necessary.
much better control of the size and shape of the toner particles. The smaller, regular, spherical particles of polymerized toners have improved flow characteristics and higher toner transfer efficiency from drum to the paper, thus giving improved image quality (See Figure 4 and 5 below).
