Popular Answers ( 2) Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 2124 % of the empty mill. Now, in order to get an efficient milling action, 80110 % of the pores in the ball bed must be filled with the actual particles to be ground. Then, by doing simple calculation, the particles occupy of the mill volume.
