The optimal ball charge in a mill has been formed in the following way 1 We define the value of the exponent in Eq 8 for the material to be ground 2 We define maximum ball diameter dbmax, according to one of the known formulae 3
Get MoreThe optimal ball diameter in a mill 331 In accordance with Eq 2, the necessary condition for grain comminution is: 2 2 3 1 bo Kd (5) So, we have got the following: the optimal ball diameter d bo is proportional to the grain diameter d to the exponent n = 067: 067 3 3 3 2 1 1 2 Kd .
