Eter and length have 14.5 greater surface area than balls of the same mass, and 9 higher bulk density than steel balls, or 12 higher than cast balls. as a result, for a given charge volume, about 25 more grinding media surface area is available for size reduction when charged with cylpebs, but the mill would also draw more power. 3 ...
Balls have a higher ratio than the other media. to realize an ideal grinding process, the largest surface area which can provide effective contact with materials is favorable. worn balls have more surface, and linear contacts, spherical media has point contact interactions
