For 60 mm (″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately D in meters (for D in feet, divide D by ). Wave height above the liners from to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.

The degree of filling the mill with balls also influences 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 3035% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
