ball mill length and diameter ratio. 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.
