The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
At first the calculations were done for 1% mill ball filling. π΄π=375.3 π=5730 π΄t=375.3Γ5730=2150469 g Aπ= 2150469 131328 =16.37 g/ton With doing the above calculations for 4% ball filling, the ball abrasion will attain 65.5 which is greater than the program ball A Method to Determine..... 19

: 3total mill volume (m ), π: number of balls which exist in mill, π΄π: each ball abrasion (g), π΄t: total ball abrasion in the mill (g), π£b: each ball volume (m3), πb: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for πb
Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; πΆπΆ3 = 2.44 π·π· 0.2 (3) However, it is important to note that C3 =0.914 vessel used in producing the ball mill was got from a
