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

Grinding in Ball Mills Modeling and Process Control

The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material (feeders) and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
