Special emphasis will be placed on the PCA that will be used (e.g. see Suryanarayana,Fig. 3), which influences the degree of agglomeration in the ball-milled materials (2001; Rigopoulos et al., 2015a,b).

Ball Mill Loading - Wet Milling - Paul O. Abbe

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
