A ball mill consists of a horizontal revolving cylinder containing a charge of tumbling or cascading balls, pebbles or rods. As a very rough indication, ball/rod charge may occupy 25–50% of the total internal volume of the mill. The length-to-diameter ratio of such a cylinder usually is between 2:1 and 3:1. Ball mills can perform wet or dry

The planetary mill pretreatment effectively reduced the size and crystallinity of the corn stover for all the ball types. Steel balls showed the highest size reduction effect in short milling time such as a 20min and alumina balls were effective at improving the surface area of the corn stover in a 60min milling time.

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.
