Ball Mill Liner Design
For 60 mm (2.5″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately 13.1 D in meters (for D in feet, divide 13.1 D by 3.3). Wave height above the liners from 1.5 to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.

Selecting a Regrind Mill
Moreover, floatability of each fraction (e.g. -400, +400-325) in mill feed and discharge was studied. Results indicated that, the floatability of all fractions in the mill feed was more than the mill discharge. It means that electrochemical interactions between the grinding media and Chalcopyrite let to decrease in floatability of material.
