tion. In 1960, the larger rod and ball mills had diameters in the range of3.20 to 3.51 m (l0.5 to 11.5 ft.). However, during the 1960s, the diameters of the mills increased to 4.57 m (15 ft) for rod mills and 5.03 m (16.5 ft) for ball mills. In addition, the diameters of the ball mills that were being designed at that time were 5.5 m (18 ft).
