8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield. The glucose yields achieved were 95.2, 75.2, 61.0, and 52.8%, for vibratory ball mill, tumbler ball mill, jet mill, and centrifugal mill, respectively

I totally agree with you that the low charge rate directly affects the grinding efficiency, but in here there is another thing we have, that shouldn''t be overlooked, it is the power consumption, at low charge rates below 20% the power consumption increase by 6-15% for the ball mills.

The mill has an optimum steel ball load value with a low unit power consumption. The specific value should be determined in the optimal loading and ball diameter ratio test of the grinding system. The production practice proves that the loading rate of the large and medium-sized tube grinding body is 25% to 35%, preferably around 30%.

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%
