THE OPTIMAL BALL DIAMETER IN A MILL
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.

Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond’s theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond’s equation is as follows: [6] where W is the work input (kWh/t); Wi is the work index
