The milling process occurs in two steps: breaking the hard structure of the cane and grinding the cane. Breaking the cane uses revolving knives, shredders, crushers, or a combination of these processes. For the grinding, or milling, of the crushed cane, multiple sets of three-roller mills are most commonly used although some mills consist of

Pyro-processing mainly consists of the head-end process, the electrolytic-reduction process, the electro-refining process, and the electro-winning process (Yoo et al., 2008). In the head-end process, used nuclear fuel assemblies are chopped up and oxidized to change them into an appropriate form as a feed for the electrolytic-reduction process.

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.
