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.
Calculate and Select Ball Mill Ball Size for Optimum Grinding
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm. dk = the P90 or fineness of the finished product in microns (um)with this the finished product is ...
