BALL MILLS. Ball mills serve as a final stage of comminution. Balls have a greater ratio of surface area to weight than rods so they are better suited to fine grinding. The length to diameter ratio ranges from less than 1 to about 1.5. Rotation speed is greater than that of rod mills, being 70–80% of critical.
