    Generally, a maximum allowed ball size is situated in the range from D/18 to D/24. The degree of filling the mill with balls also influences the productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drumBall Mills Mineral Processing & Metallurgy,The capacities, power requirements, etc., of the various sizes of Hardinge Ball Mills are given in Table 12.
